LD8526 Overview
LD8526 is a secondary side synchronous rectification (SR) driver IC. It is suited for flyback low side and high side synchronous rectification in CCM, DCM and QR mode. For forward freewheeling rectification application, LD8526 can be applied in CCM and DCM operation.
LD8526 Key Features
- Suited for low side and high side flyback synchronous rectification in CCM, DCM and QR(valley lock) mode
- Suited for forward freewheeling rectification in CCM and DCM
- Self-supplying for operation with low output voltage and/or high-side rectification without an auxiliary winding
- Suited for primary side with peak load function (max. frequency 130kHz)
- Suited for PD application, which output voltage range from 3V to 21V, and VCC range from 3V to 6V
- Programmable turn-off level
- Fast turn-off total delay of 30ns
- 200A ultra-low green mode operation current
- Gate source/sink capability: 0.5A/-3A
