Description
Each product in the FSDx0365RN (x for L, M) family consists
of an integrated Pulse Width Modulator (PWM) and Sense
FET, and is specifically designed for high performance off-line
Switch Mode Power Supplies (SMPS) with minimal external
components. Both devices are integrated high voltage power
switching regulators which combine an avalanche rugged
Sense FET with a current mode PWM control block. The inte-
grated PWM controller features include: a fixed oscillator with
frequency modulation for reduced EMI, Under Voltage Lock
Out (UVLO) protection, Leading Edge Blanking (LEB), an
optimized gate turn-on/turn-off driver, Thermal Shut Down
(TSD) protection, Abnormal Over Current Protection (AOCP)
and temperature compensated precision current sources for
loop compensation and fault protection circuitry. When com-
pared to a discrete MOSFET and controller or RCC switching
converter solution, the FSDx0365RN devices reduce total
component count, design size, weight while increasing effi-
ciency, productivity and system reliability. Both devices pro-
vide a basic platform that is well suited for the design of cost-
