Description

The FSL116LR integrated Pulse Width Modulator

(PWM) and SenseFET is specifically designed for high-

performance offline Switch-Mode Power Supplies

(SMPS) with minimal external components. FSL116LR

includes

integrated

high-voltage

power

switching

regulators

that

combine

an

avalanche-rugged

SenseFET with a current-mode PWM control block.

The integrated PWM controller includes: Under-Voltage

Lockout (UVLO) protection, Leading-Edge Blanking

(LEB), a frequency generator for EMI attenuation, 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. The

FSL116LR offers good soft-start performance. When

compared to a discrete MOSFET and controller or RCC

switching converter solution, the FSL116LR reduces

total component count, design size, and weight; while

increasing efficiency, productivity, and system reliability.

This device provides a basic platform that is well suited

for the design of cost-effective flyback converters.
