FSBH0270NY_F116 Datasheet PDF - Fairchild

●Description

●The highly integrated FSBH-series consists of an integrated current-mode Pulse Width Modulator (PWM) and an avalanche-rugged 700V SenseFET. It is specifically designed for high-performance offline Switched-Mode Power Supplies (SMPS) with minimal external components.

●Features

●  Brownout Protection with Hysteresis

●  Built-In 5ms Soft-Start Function

●  Internal Avalanche-Rugged 700V SenseFET

●  Low Acoustic Noise During Light-Load Operation

●  High-Voltage Startup

●  Linearly Decreasing PWM Frequency to 18KHz

●  Peak-Current-Mode Control

●  Cycle-by-Cycle Current Limiting

●  Leading-Edge Blanking (LEB)

●  Synchronized Slope Compensation

●  Internal Open-Loop Protection

●  VDDUnder-Voltage Lockout (UVLO)

●  VDDOver-Voltage Protection (OVP)

●  Internal Auto-Restart Circuit (OVP, OTP)

●  Constant Power Limit (Full AC Input Range)

●  Internal OTP Sensor with Hysteresis

●  VIN Pin for Pull-HIGH Latch Function and Pull-LOW Auto-Recovery Protection

●Applications

●General-purpose switched-mode power supplies and flyback power converters, including:

●  Auxiliary Power Supply for PC and Server

●  SMPS for VCR, SVR, STB, DVD & DVCD Player, Printer, Facsimile, and Scanner

●  Adapter for Camcorder
