Silan SD4943S 150V NON-ISOLATED DC TO DC CONTROLLER

Product Description

SD4943S is a current - mode PWM controller with a built - in 150V high - voltage MOSFET for switching power supplies. It will enter the burst mode under light load, thus effectively reducing the standby power dissipation of the system.

      The SD4943S features high - voltage start - up, self - power supply, frequency reduction, and soft start. Various protection functions, it also integrates various protections including: VDD undervoltage protection, VDD overvoltage protection, output overload protection, output short - circuit protection, over - temperature protection, etc. After the protection is triggered, the circuit will automatically restart until the system is normal.

Specification

16V~150V input voltage	Optimized load regulation
Adjustable output voltage	Soft startup
High-voltage self-power	VDD undervoltage protection
Frequency reduction at light load condition	Output overvoltage protection
Over temperature protection	Output overload protection
