TOP250Y [Power Integrations]

TOPSwitch-GX family extends the power range and design flexibility of TOPSwitch, integrating a high voltage power MOSFET, PWM control, fault protection, and control circuitry on a single chip. It features extended power range (up to 290W for open frame), no heatsink required up to 34W, reduced external components, fully integrated soft-start, externally programmable current limit, wider duty cycle (78% max), line sensing (UV/OV), line feed-forward, frequency jittering for EMI reduction, 132 kHz switching frequency (with half-frequency option), hysteretic thermal shutdown, and EcoSmart energy efficiency (low off-mode power, frequency scaling for standby).
