SL3150 150V Non-Isolated Off-line Regulator up to 400mA Output Current

GENERAL DESCRIPTION 

SL3150 is a Buck regulator that provides accurate constant voltage (CV) regulation without opto-coupler. It has an integrated 150V MOSFET to simplify the structure and reduce costs. These features make it an ideal regulator for off-line low power applications, such as home appliances and standby power. 

SL3150 is a green -mode-operation regulator. Both the peak current and switching frequency decrease as the load decreases. This feature provides excellent efficiency at light load, and improves the overall average efficiency. SL3150 features various protections, including thermal shutdown (OTP), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open loop protection. 

SL3150 is offered in SOP7 package.
