Power Integrations Launches TinySwitch-5 ICs for High-Efficiency Power Supplies

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.”

NEW DELHI (AP) — Authorities imposed an indefinite curfew in parts of a western Indian city on Tuesday, a day after sectarian clashes were sparked by Hindu nationalist groups who want to demolish the tomb of a 17th-century Muslim Mughal ruler.

Clashes between Hindus and Muslims in Maharashtra state’s Nagpur city broke out on Monday during a protest led by Hindu nationalist groups demanding the demolition of the tomb of Aurangzeb, a Muslim Mughal ruler who has been dead for more than 300 years.

Lawmaker Chandrashekhar Bawankule said at least 34 police personnel and five other people were injured and several houses and vehicles were damaged during the violence. Senior police office Ravinder Singal said at least 50 people have been arrested so far.

Devendra Fadnavis, Maharashtra’s top elected official, said the violence began after “rumors were spread that things containing religious content were burnt” by the protesters, referring to the Quran.

Aurangzeb’s tomb is in Chhatrapati Sambhaji Nagar city, some 500 kilometers (310 miles) from Nagpur. The city was earlier called Aurangabad, after the Mughal ruler.

Aurangzeb is a loathed figure among India’s Hindu nationalists, who accuse him of persecuting Hindus during his rule in the 17th century, even though some historians say such stories are exaggerated.

As tensions between Hindus and Muslims have mounted under Hindu nationalist Prime Minister Narendra Modi, scorn for Aurangzeb has grown. Modi has made references to Aurangzeb in the past, accusing him of persecuting Hindus.

Such remarks have led to anxieties among the country’s significant Muslim minority who in recent years have been at the receiving end of violence from Hindu nationalists, emboldened by a prime minister who has mostly stayed mum on such attacks since he was first elected in 2014.

Tensions over the Mughal ruler have intensified in India after the release of Bollywood movie “Chhaava,” an action film based on a Hindu warrior who fought against Aurangzeb. The film has been lambasted by some movie critics for feeding into a divisive narrative that risks exacerbating religious rifts in the country.

While there have long been tensions between India’s majority Hindu community and Muslims, rights groups say that attacks against minorities have become more brazen under Modi. They also accuse Modi of discriminatory policies towards the country’s Muslims.

Modi’s ruling Hindu nationalist Bharatiya Janata Party denies this.

Hindu extremists have also targeted Muslim places of worship across the country and laid claim to several famous mosques, arguing they are built on the ruins of prominent temples. Many such cases are pending in courts.

Last year, Modi delivered on a longstanding demand from Hindu nationalists — and millions of Hindus — when he opened a controversial temple on the site of a razed mosque in northern India’s Ayodhya city. The 16th-century Babri mosque was demolished in 1992 by Hindu mobs who believe Ram, one of Hinduism's most revered deity, was born at the exact spot.
