Description

This document describes the design example of a power supply using the STR6A161HVD intended for the isolatedflyback converter that supports universal inputs and a 12 V/1.0 A output. The STR6A161HVD is a current mode PWMcontrol IC with a built-in power MOSFET. In addition, the design example uses the SARS05 as a diode for the resistorcapacitor-diode (RCD) snubber, the SJPX-F2 as a fast recovery diode for the IC’s power supply, and the SJPE-T15 as aSchottky diode for the secondary rectifier.This document contains the following: the specifications of the design example, circuit diagrams, the bill of materials,the setting examples of component constants, a pattern layout example, and the evaluation results of the power supply characteristics. For more details on the parts listed in this document, refer to the corresponding data sheets.

Features

  • Improved Circuit Efficiency (Secondary Rectifier Diodes with Lower VRM and VF Characteristics Achieved by Step Drive Control Circuit)
  • Adjustable Standby Operating Point
  • Reduced Number of External Components (Built-in Startup Circuit)
  • High Efficiency in All Load Ranges Achieved by Load-based Auto-shifting Operation Modes
  • Normal Operation: PWM Mode, 100 kHz(Typ.)
  • Light-load Operation: Green Mode
  • Standby Operation: Burst Oscillation Mode
  • Efficiency: 84% (230 VAC, 12 W)
  • Input Power at No Load: 32 mW (230 VAC)
  • Reduced EMI Noise (Random Switching Function)

Typical applications

  • Auxiliary Power Supply, Power Supply for Motor Control, Other SMPSs (Switching Mode Power Supplies)
  • Small Home Appliance, Large Home Appliance
