Description

The HiperLCS™-2 family of IC chipsets dramatically simplifies the design and manufacture of LLC resonant power converters, particularly those requiring high efficiency and/or compact size and delivering up to 220 W continuous output power with no heat sink. The HiperLCS2-HB (LCS72xxC) primary-side devices incorporate 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.

HiperLCS-2 family devices incorporate multiple protection features including: line over 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,
