Description
A Valley Switching Converter (VSC) generally shows
lower EMI and higher power conversion efficiency than
a conventional hard-switched converter with a fixed
switching frequency. The FSQ510 (H or M) is an
integrated valley switching pulse width modulation (VS-
PWM) controller and SenseFET specifically designed
for offline switch-mode power supplies (SMPS) for
valley switching with minimal external components. The
VS-PWM controller includes an integrated oscillator,
under-voltage lockout (UVLO), leading-edge blanking
(LEB),
optimized
temperature-compensated precise current sources for
loop compensation, and self-protection circuitry.
Compared with discrete MOSFET and PWM controller
solutions, the FSQ510 (H or M) can reduce total cost,
component count, size and weight; while simultaneously
increasing efficiency, productivity, and system reliability.
This device provides a platform for cost-effective designs
of a valley switching flyback converters.
