TOP412 Datasheet Three-terminal DC To DC Pwm Switch

Manufacturer: Power Integrations

Overview: TOP412/414 TOPSwitch Family Three-terminal DC to DC PWM Switch Product Highlights Low Cost Replacement for Discrete Switchers • Up to 15 fewer ponents - cuts cost, increases reliability • Allows for a smaller and.

General Description

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 pensation and fault protection circuitry.

pared to discrete MOSFET and controller or self oscillating (RCC) switching converter solutions, a TOPSwitch integrated circuit can reduce

Key Features

  • 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 D.
