FSD146MRBN - Green-Mode Fairchild Power Switch

General Description

The FSD146MRBN is an integrated Pulse Width Modulation (PWM) controller and SenseFET designed for offline Switch-Mode Power Supplies (SMPS) with minimal external components.

Key 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), Internal Thermal Shutdown (TSD) with Hysteresis, Output-Short Protection (OSP), and Under-Voltage Lockout (UVLO) with Hysteresis Low Operating Current (0.4mA) in Burst Mode Internal Startup Circuit.
