Description
A Valley 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 that is well suited for cost-
effective designs of valley switching fly-back converters.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. TA = 25°C, unless otherwise specified.
