Power Integrations INN5376F-H901 | Demoboard DER-1001

Beschreibung

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.
