Description
The FSCM0465R is an integrated Pulse-Width
Modulator (PWM) and SenseFET specifically designed
for high-performance offline Switch Mode Power
Supplies (SMPS) with minimal external components.
This device is an integrated high-voltage power-
switching regulator that combines an avalanche rugged
SenseFET with a current mode PWM control block. The
PWM controller includes an integrated fixed-frequency
oscillator, under-voltage lockout, leading edge blanking
(LEB), optimized gate driver, internal soft-start,
temperature-compensated precise current sources for a
loop compensation, and self-protection circuitry.
Compared with a discrete MOSFET and PWM controller
solution, it can reduce total cost, component count, size,
and weight while simultaneously increasing efficiency,
productivity, and system reliability. This device is a basic
platform well suited for cost-effective designs of flyback
converters.

Pin Function Description
SenseFET Drain. This pin is the high-voltage power SenseFET drain. It is
designed to drive the transformer directly.
Ground. This pin is the control ground and the SenseFET source.
Power Supply. This pin is the positive supply voltage input. During startup,
the power is supplied through the startup resistor from DC link. When VCC
reaches 12V, the power is supplied from the auxiliary transformer winding.
Feedback. This pin is internally connected to the inverting input of the PWM
comparator. The collector of an opto-coupler is typically tied to this pin. For
stable operation, a capacitor should be placed between this pin and GND. If
the voltage of this pin reaches 6.0V, the overload protection is activated, re-
sulting in shutdown of the FPS.
This pin is not connected.
Current Limit. This pin is for the pulse-by-pulse current limit level program-
ming. By using a resistor to GND on this pin, the current limit level can be
changed. If this pin is left floating, the typical current limit is 2.0A.
