Description

This design engineering report describes a power supply using InnoSwitch5-Pro INN5376F-H901 IC. This report primarily presents the design and implementation of a programmable wide-output voltage power supply, utilizing a generic micro controller (in this case Microchip PIC16F18325) for control.The microcontroller controls the InnoSwitch5-Pro via an I2C interface, programming its command and telemetry registers. This design dynamically adjusts the rated output power capability for both high and low line by utilizing secondary-side input line sensing feature in the InnoSwitch5-Pro IC.This report contains the power supply specification, schematic diagram, printed circuit board layout, bill of materials, transformer documentation, and performance data. The firmware used with this report enables constant voltage (CV), constant current (CC), and constant power modes (CP) available with the InnoSwitch5-Pro family.

Features

  • Comprehensive protection features with fault monitoring and telemetry reporting of power supply status.
  • Advanced SR FET control enables Zero voltage switching (ZVS) across line and output voltage range.
  • Easily meets DOE6 and CoC v5 2016 average efficiency requirements
  • 5 V output: 92.5% at 115 VAC (16.25 W) (10.7% margin);92.6% at 230 VAC (25 W) (10.8% margin)
  • 20 V output: 92.3% at 115 VAC (65 W) (3.3% margin); 93.5% at 230 VAC (100 W) (4.49% margin)
  • 28 V output: 91% at 115 VAC (65 W) (2.05% margin);92.8% at 230 VAC (100 W) (3.81% margin)
  • Meets CoC v5 2016 10% requirements with >8% margin
  • <35 mW no-load input power at 230 VAC
  • Easily meets CISPR22 / EN55022 Class B conducted EMI

  • 5 dB margin -worst case (28 V / 3.57 A (100 W), 230 VAC)

  • High power density: 11.13 W / in3 without enclosure 3.31” x 2.95” x 0.92” form factor
  • Only 84 electrical components

Typical applications

  • Programmable Industrial Power Supply
