FSQ0365R - Switched-Mode Power Supply, 15Vsupply, 55.6 kHz, 700V, DIP-8

Descrição geral do produto
The FSQ0365RN is a Switching Converter generally shows lower EMI and higher power conversion efficiency than a conventional hard-switched converter with a fixed switching frequency. The FSQ-series is an integrated pulse-width modulation (PWM) controller and SenseFET specifically designed for valley switching operation with minimal external components. The PWM controller includes an integrated fixed-frequency oscillator, under-voltage lockout, leading-edge blanking (LEB), optimized gate driver, internal soft-start, temperature-compensated precise current sources for loop compensation and self-protection circuitry. Compared with discrete MOSFET and PWM controller solutions, the FSQ-series reduces total cost, component count, size and weight; while simultaneously increasing efficiency, productivity and system reliability. This device provides a basic platform for cost-effective designs of valley switching fly-back converters.
