Products Detail

The TOPSwitch family integrates all functions necessary for a DC-DC converter: high-voltage N-channel power MOSFET, controlled turn-on gate driver, voltage-mode PWM controller with 120 kHz oscillator, high-voltage start-up bias, bandgap reference, bias shunt regulator/error amplifier for loop compensation, and fault protection. It reduces total cost, component count, size, weight, and increases efficiency and reliability compared to discrete solutions. Supports multiple topologies (Buck, Boost, Flyback, Forward) and feedback methods. Features include auto-restart, cycle-by-cycle current limiting, thermal shutdown, and operation down to 16V DC input. Only one external capacitor is needed for compensation, bypass, and start-up functions.

Key Features

Low cost, fewer components (up to 15 less), small size (<12 mm height), high efficiency (>80%), built-in start-up and current limit, low capacitance MOSFET, CMOS controller (7 mW power), 70% max duty cycle, integrated PWM controller and MOSFET, only one external capacitor, auto-restart, cycle-by-cycle current limiting, thermal shutdown, supports multiple topologies, interfaces with opto/primary feedback, continuous/discontinuous mode, 16V DC input operation
