Description
The FSQ500N is specially designed for low cost, small
set-top box, DSL, home appliance auxiliary power
supplies. This device combines a current-mode Pulse
Width Modulator (PWM) with a SenseFET. The
integrated PWM controller features include: a fixed
oscillator, Under-Voltage Lockout (UVLO) protection,
Overload Protection (OLP), Leading-Edge Blanking
(LEB), an optimized gate turn-on/turn-off driver,
Thermal Shutdown (TSD) protection with hysteresis,
and temperature-compensated precision-current
sources for loop compensation. When compared to a
linear power supply, the FSQ500N reduces total size
and weight, while increasing efficiency, productivity, and
system reliability. This device provides a basic platform
for cost-effective flyback converters.
