Description

Description
The FSD200 and FSD210 are integrated Pulse Width Modulators (PWM) and Sense FETs specially designed for high performance off-line Switch Mode Power Supplies (SMPS) with minimal external components. Both devices are monolithic high voltage power switching regulators which combine an LDMOS Sense FET with a voltage mode PWM control block. The integrated PWM controller features in clude: a fixed oscillator with frequency modulation for reduced EMI, Under Voltage Lock Out (UVLO) protection, Leading Edge Blanking (LEB), optimized gate turn-on/turn off driver, thermal shut down protection (TSD), temperature compensated precision current sources for loop compensation and fault protection circuitry. When compared to a discrete MOSFET and controller or RCC switching converter solution, the FSD200 and FSD210 reduce total component count, design size, weight and at the same time increase efficiency, productivity, and system reliability. The FSD200 eliminates the need for an auxiliary bias winding at a small cost of increased supply power. Both devices are a basic platform well suited for cost effective designs of flyback converters.

Features
• Single Chip 700V Sense FET Power Switch
• Precision Fixed Operating Frequency (134kHz)
• Advanced Burst-Mode operation Consumes under 0.1W at 265Vac and no load (FSD210 only)
• Internal Start-up Switch and Soft Start
• Under Voltage Lock Out (UVLO) with Hysteresis
• Pulse by Pulse Current Limit
• Over Load Protection (OLP)
• Internal Thermal Shutdown Function (TSD)
• Auto-Restart Mode
• Frequency Modulation for EMI
• FSD200 does not require an auxiliary bias winding

Applications
• Charger & Adaptor for Mobile Phone, PDA & MP3
• Auxiliary Power for White Goods, PC, C-TV & Monitor
