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.
