Description
The FSQ0170RNA, FSQ0270RNA, FSQ0370RNA
consists of an integrated current mode Pulse Width
Modulator (PWM) and an avalanche-rugged 700V Sense
FET. 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 FSQ0170RNA,
FSQ0270RNA, FSQ0370RNA 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, as in PC
auxiliary power supplies.
