Product Details

Description

The HiperLCS™-2 chipset achieves high efficiency and compact size in power supplies up to 220 W without a heat sink and up to 1650 W with a heat sink. This IC chipset simplifies the design and manufacture of LLC resonant power converters. The HiperLCS2-HB (LCS726x) primary-side devices incorporate a 600 V FREDFET in a half-bridge arrangement with control, level shifting, drive, and self-powered start-up. The HiperLCS2-SR (LSR2000C) master controller device provides reinforced isolated feedback, output sensing, and SR management.

The HiperLCS-2 chipset incorporates multiple protection features, including line overvoltage and undervoltage protection, output overvoltage, and over-temperature shutdown. Device fault response options support common combinations of latching and auto-restart behaviors required by applications such as chargers, adapters, consumer electronics, and industrial systems.
