TOP414
Overview
The TOPSwitch family implements, with only three terminals, all functions necessary for a DC to DC, converter: high voltage N-channel power MOSFET with controlled turn-on gate driver, voltage mode PWM controller with integrated 120 kHz oscillator, high voltage start-up bias circuit, bandgap derived reference, bias shunt regulator/error amplifier for loop compensation and fault protection circuitry. Compared to discrete MOSFET and controller or self oscillating (RCC) switching converter solutions, a TOPSwitch.
- Auto-restart and cycle by cycle current limiting functions handle both primary and secondary faults
- On-chip latching thermal shutdown protects the entire system against overload Highly Versatile
- Implements Buck, Boost, Flyback or Forward topology
- Easily interfaces with both opto and primary feedback
- Supports continuous or discontinuous mode of operation
- Specified for operation down to 16 V DC input VIN
