Typical Circuit

Description

In general, a Quasi-Resonant Converter (QRC) shows lower

EMI and higher power conversion efficiency compared to

conventional hard-switched converter with a fixed switching

frequency. Therefore, a QRC is well suited for noise-

sensitive applications, such as color TV and audio. Each

product in the FSCQ-Series contains an integrated Pulse

Width Modulation (PWM) controller and a SenseFET, and

is specifically designed for quasi-resonant off-line Switch

Mode Power Supplies (SMPS) 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 a loop

compensation, and self protection circuitry. Compared with a

discrete MOSFET and PWM controller solution, the FSCQ-

Series can reduce total cost, component count, size, and weight,

while simultaneously increasing efficiency, productivity, and

system reliability. These devices provide a basic platform

that is well suited for cost-effective designs of quasi-resonant

switching flyback converters.
