ATLANTA--(BUSINESS WIRE)--Mar 17, 2025--
APEC 2025 – Power Integrations (NASDAQ: POWI ), the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced TinySwitch™-5, extending the output power of the most popular family of integrated off-line switcher ICs to 175 W. The new TinySwitch-5 achieves up to 92 percent efficiency using basic diode rectification and optocoupler feedback.

With more than six billion units sold around the world, TinySwitch ICs are widely used in bias and auxiliary supplies in appliance, computing, communications, industrial and medical applications. Designers have long appreciated TinySwitch products for their design simplicity and high efficiency—particularly at light load. TinySwitch ICs were the first to feature Power Integrations’ award-winning EcoSmart™ technology, which has saved an estimated 200 terawatt-hours of electricity since 1998 by slashing standby power waste.
TinySwitch-5 switcher ICs feature an advanced control engine which seamlessly manages switching frequency and power delivery to maximize efficiency, even at light loads. This enables power supplies that easily meet the light-load power consumption limit of 300 mW, set by the European Commission Energy-related Products (ErP) Directive 2009/125/EC, while still delivering up to 220 mW output power for display, controls and communications functions. An enhanced thermal package means that TinySwitch-5 ICs can deliver up to 75 W without a heatsink, and line under- and over-voltage protection ensures robustness for use in countries with unstable mains power.
Silvestro Fimiani, director of product marketing at Power Integrations, said: “TinySwitch has become the gold standard for small power supplies because of its efficiency and ease of use. With TinySwitch-5, designers can scale up to 175 W at maximum power, while easily achieving 220 mW of output and meeting the needs of appliance manufacturers subject to the European Union ErP-mandated 300 mW standby power rule.”
Availability & Resources
Pricing for TinySwitch-5 starts at $0.35 for 10,000-unit quantities. Reference designs are available which describe: a 12 W single-output power supply ( DER-1017 ); a 26.5 W dual-output power supply with excellent standby efficiency ( RDR-1016 ); a 36 W single-output power supply with high efficiency at light load ( DER-1040 ); and a 120 W power supply with 92 percent efficiency at 230 V AC ( DER-1027 ).

FRANKFORT, Ky. (AP) — Kentucky Democratic Gov. Andy Beshear vetoed a GOP-backed bill Thursday to dismantle diversity, equity and inclusion efforts at public universities, declaring that diversity should be embraced as a strength while branding the legislation as being “about hate.”
Beshear, who is seen as a potential candidate for the White House in 2028, announced his veto in a social media video. His forceful defense of diversity initiatives comes as Republican President Donald Trump seeks to end government support for programs promoting diversity, equity and inclusion.
“I believe in the Golden Rule that says we love our neighbor as ourself, and there are no exceptions, no asterisks,” Beshear said. "We love and we accept everyone. This bill isn’t about love. House Bill 4 is about hate. So I’m gonna try a little act of love myself, and I’m gonna veto it right now.”
In his formal veto message, the governor bluntly said the bill might someday be seen as part of an “anti-civil rights” movement.
The anti-DEI legislation cleared both legislative chambers by lopsided margins. Kentucky's Republican supermajority legislature will have a chance to override Beshear's veto when lawmakers reconvene in late March for the final two days of this year's 30-day session. Throughout Beshear's tenure as governor, GOP lawmakers have, with gusto, routinely swept aside his vetoes to push their policies into law.
Republican state Rep. Josh Calloway denounced Beshear's veto on the social media platform X, calling it “nothing but political theater, and the people of Kentucky see right through it. DEI (Division, Exclusion, Indoctrination) must DIE in KY.”
The measure's lead sponsor, GOP state Rep. Jennifer Decker, said at a recent committee hearing that “DEI bureaucracy” had made college "more divided, more expensive and less tolerant.”
“Taxpayers should not fund such practices, however well-intended," she said. "Historically, America has striven for equal opportunity, not subjective equity, which DEI now pursues through discriminatory missions, hirings and scholarships.”
Kentucky Senate Democratic Floor Leader Gerald Neal commended Beshear for the veto, saying the bill would "do nothing to improve education in this state, but would instead send a harmful message that diversity is something to be feared rather than embraced.”
The measure Beshear rejected would require Kentucky's public universities and community and technical colleges to defund DEI initiatives. It also would require the schools to eliminate DEI offices and prohibit them from requiring students or staff to attend DEI training sessions.
“I’ll always believe that diversity is a strength and never a weakness,” Beshear said in the video from his office at the Kentucky Capitol. “That we are better with more voices and more seats at our table.”
More than 50 universities are being investigated for alleged racial discrimination as part of Trump’s campaign to end DEI programs, which his officials say exclude white and Asian American students.
The U.S. Education Department recently announced the new investigations, one month after issuing a memo warning America’s schools and colleges that they could lose federal money over “race-based preferences” in admissions, scholarships or any aspect of student life.
Trump signed an executive order Thursday aimed at eliminating the U.S. Education Department, advancing a campaign promise to eliminate an agency blasted by conservatives as wasteful and polluted by liberal ideology. Beshear has criticized efforts to mothball the agency.
The term-limited Kentucky governor recently participated in a march across the Edmund Pettus Bridge in Selma, Alabama, to mark the 60th anniversary of the clash that became known as Bloody Sunday. The attack shocked the nation and galvanized support for the U.S. Voting Rights Act of 1965.
Last year, Beshear condemned efforts to limit DEI practices at public universities after marching with other Kentuckians to commemorate the 60th anniversary of a civil rights rally that featured Martin Luther King Jr. in the state’s capital city of Frankfort. Anti-DEI legislation died last year in Kentucky amid a House-Senate impasse in what was a rare temporary setback on a priority, hot-button issue.
“DEI is not a four-letter word,” Beshear said at the time. “DEI is a three-letter acronym for very important values that are found in our Bible. Diversity, equity and inclusion is about loving each other. It’s about living out the Golden Rule. ... Diversity will always make us stronger.”
