Description
The FSDL0165RN is an integrated Pulse Width Modulator
(PWM) and Sense FET specifically designed for high perfor-
mance offline Switch Mode Power Supplies (SMPS) with
minimal external components. This device is an integrated
high voltage power switching regulator which combine an
avalanche rugged Sense FET with a current mode PWM
control block. The integrated PWM controller features
include: a fixed oscillator with frequency modulation for
reduced EMI, Under Voltage Lock Out (UVLO) protection,
Leading Edge Blanking (LEB), optimized gate turn-on/turn-
off driver, Thermal Shut Down (TSD) protection, Abnormal
Over Current Protection (AOCP) and temperature compen-
sated precision current sources for loop compensation and
fault protection circuitry. When compared to a discrete
MOSFET and controller or RCC switching converter solu-
tion, the FSDL0165RN reduce total component count,
design size, weight and at the same time increases efficiency,
productivity, and system reliability. This device is a basic
platform well suited for cost effective designs of flyback
converters.
