LCS7265C
HiperLCS-2 is a high efficiency, off-line LLC Switcher IC Chipset. It consists of:
- HiperLCS2-HB, a Half-bridge Power Device with Integrated 600 V FREDFETs, and
- HiperLCS2-SR, a Safety Isolation Device with Synchronous Rectification and FluxLink Feedback
Note: HiperLCS-2 can easily pair with the HiperPFS-5 PFC IC.
Product Details
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,
