    Products Detail

    The TOP242-250 family integrates a high-voltage power MOSFET, PWM control, fault protection, and control circuitry on a single chip. It offers extended power range, design flexibility, and EcoSmart energy efficiency. Additional pins in certain packages enable functions like line sensing (OV/UV), externally programmable current limit, remote ON/OFF, synchronization, and frequency selection. Features include integrated soft-start, frequency jittering for reduced EMI, hysteretic thermal shutdown, and light-load frequency reduction for high standby efficiency. The device reduces system costs by minimizing external components.

    Key Features

    • Extended power range, no heatsink required up to 34W, fully integrated soft-start, externally programmable current limit, wider duty cycle, line under-voltage detection, line overvoltage shutdown, line feed-forward, frequency jittering, regulates to zero load, 132 kHz frequency, half frequency option, hysteretic thermal shutdown, EcoSmart energy efficient, low consumption in remote off mode, frequency lowered with load for high standby efficiency, allows shutdown/wake-up via LAN/input port
