Description
The FSQ100 consists of an integrated Pulse Width
Modulator (PWM) and SenseFET, specifically designed
for high-performance, off-line, Switch-Mode Power
Supplies (SMPS) with minimal external components.
This device is an integrated high-voltage power
switching regulator that combines a VDMOS SenseFET
with a voltage mode PWM control block. The integrated
PWM controller features include a fixed oscillator,
Under-Voltage Lockout (UVLO) protection, Leading
Edge Blanking (LEB), an optimized gate turn-on/turn-off
driver, Thermal Shutdown (TSD) protection, and
temperature-compensated precision-current sources for
loop compensation and fault protection circuitry.
When compared to a discrete MOSFET and controller or
RCC solution, the FSQ100 device reduces total
component count and design size and weight, while
increasing efficiency, productivity, and system reliability.
This device provides a basic platform well suited for
cost-effective flyback converters.
