LD8921Synchronous Rectification Driver with 45V Low RDS(ON) N-MOSFET

LD8921 is a secondary side Synchronous Rectification (SR) driver IC in DCM operation. It combines a low voltage drop N-channel MOSFET to improve efficiency and reduce heat from secondary-side rectifier.
LD8921 can work with low system output voltage which goes down to 3V in the constant current mode. LD8921 integrates programmable turn-off level. Furthermore, it responds quickly to the dynamic load in PSR topology.
