ICE1HS01G-1

Overview

Infineon ICE1HS01G resonant mode converter, housed in a DSO-8 package, is an easy-to-design to realize a LLC HB resonant application. An oscillator is built-in allowing designers to set the suitable operation frequency range with a resistor. In addition, ICE1HS01G offers a programmed soft-start function to limit both the inrush current and the overshoot in output voltage. To protect the system during operation, mains input under-voltage protection and over-current protection are also in-built. Hence, it is able to operate in resonant mode with the highest reliability possible.
