FSD146MRBN Datasheet - Fairchild Semiconductor

FSD146MRBN Green-Mode Fairchild Power Switch

The FSD146MRBN is an integrated Pulse Width Modulation (PWM) controller and SenseFET designed for offline Switch-Mode Power Supplies (SMPS) with minimal external components. The PWM controller includes an integrated fixed-frequency oscillator, UnderVoltage Lockout (UVLO), Leading-Edge Blanking (LEB).

FSD146MRBN Features

* Advanced Soft Burst-Mode Operation for Low Standby Power and Low Audible Noise Random Frequency Fluctuation for Low EMI Pulse-by-Pulse Current Limit Various Protection Functions: Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal Over-Current Protection (AOCP)
