Description

The FSQ0170RNA is an integrated current mode Pulse Width Modulator (PWM) and an avalanche-rugged 700V Sense FET. It is specifically designed for high-performance offline switch mode power supplies (SMPS) with minimal external components. The integrated PWM controller features a fixed-frequency generating oscillator, under-voltage lockout (UVLO) protection, leading edge blanking (LEB), an optimized gate turn-ON/OFF driver, thermal shutdown (TSD) protection and temperature compensated precision current sources for loop compensation and fault protection circuitry. Compared to a discrete MOSFET and controller or RCC switching converter solution, the FSQ0170RNA reduces total component count, design size and weight while increasing efficiency, productivity and system reliability. These devices provide a basic platform that is well suited for the design of fly-back converters, as in PC auxiliary power supplies.
Internal start-up circuit and built-in soft-start
Pulse-by-pulse current limiting and auto-restart mode
Over-voltage protection, overload protection and internal thermal shutdown function
Adjustable peak current limit
100kHz Precision fixed operating frequency
