Synchronous FET Controller

HIGH RELIABILITY PRODUCTS

Features

Description

TS4305BM is a synchronous rectifier controller for AC-DC

power supply’s secondary side rectification.



Current-sense control for low or high-side

synchronous rectifiers

Rectifier turn on/off thresholds set with external

resistors

Minimum ON and OFF time to minimize GATE turn-

on oscillation

Specifications



Drives low or high side N-channel MOSFET

Sync-FET control based on current sensing in low or

high-side sense resistor



Wide supply range 8V to 24V

Gate drive internally limited to 10V

2A sink, 1A source gate drive

4mm x 5mm SOIC-8 package

Product is lead-free, Halogen Free, RoHS / WEEE



-55°C to +125°C T_Joperation

Operation to 24V

2A/1A sink/source gate drive

10V gate drive capability

100ns propagation delay between current sense to

GATE drive
