Description
The FSQ110 consists of an integrated, current-mode,
Pulse Width Modulator (PWM) and an avalanche-rugged
650V SenseFET. It is specifically designed for high-
performance off-line Switch-Mode Power Supplies
(SMPS) with minimal external components.
The integrated PWM controller features include: a fixed-
frequency generating 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.
Compared to a discrete MOSFET and controller or RCC
switching converter solution, the FSQ110 reduces total
component count, design size, and weight while
increasing efficiency, productivity, and system reliability.
These devices provide a basic platform that is well suited
for the design of cost-effective flyback converters.

Notes:
10. These parameters, although guaranteed, are not 100% tested in production.
11. Pulse test: Pulse width ≤ 300µs, duty ≤ 2%.
12. The ESD level of an existing product can be applied to FSQ110 because it has same ESD protection circuit.
