TOP244Y [Power Integrations]

TOPSwitch-GX integrates a high-voltage power MOSFET, PWM control, fault protection, and control circuitry onto a single CMOS chip. It reduces system cost and improves design flexibility, performance, and energy efficiency. Features include extended power range, no heatsink required up to 34W with P/G packages, fully integrated soft-start, externally programmable current limit, wider duty cycle, line sensing, under-voltage/overvoltage detection, frequency jittering, zero-load regulation, 132 kHz switching frequency, hysteretic thermal shutdown, and EcoSmart energy efficiency.
