SD4945

150V NON-ISOLATED DC TO DC CONTROLLER

Description Main feature Product specification classification Internal block diagram Technical documentation Relevant package outline drawing

SD4945 is DC-DC controller with built-in 150V high-voltage MOSFET used for SMPS.

SD4945 integrates high-voltage circuit and self-power function for fast startup and low standby power dissipation. It features the frequency reduction function to optimize the conversion efficiency at light load; the soft startup function reduces the device stress to avoid transformer saturation.

SD4945 integrates various protections, including VDD undervoltage protection, output overload protection, output overvoltage protection, over temperature protection, etc. Meanwhile, if any protection occurs, the circuit will continue to restart automatically until the system recovers.

Main feature

18V~150V input voltage
Adjustable output voltage
High-voltage startup
Frequency reduction at light load condition
Optimized load regulation
Soft startup
VDD undervoltage protection
Output overvoltage protection
Lead edge blanking
Output overload protection
