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. FEATURES Primary-Side CV control. Wide input range: 15V~150V Integrated 150V/5.0Ω MOSFET and current source < 30mW no-load power consumption Fixed 5.0V output voltage Up to 400mA output Current Low VCC Operating Current Frequency foldback Limited maximum frequency Internally biased VCC OTP, UVLO, OLP, SCP, Open loop APPLICATIONS Standby power E-bike applications Industrial controls Consumer electronics TYPICAL APPLICATION |
