Description
The FSDM0465RE, FSDM0565RE and FSDM07652RE
are 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.

Description
SenseFET drain.
This pin is the high-voltage power SenseFET drain. It is de-
signed 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 start-up,
the power is supplied by an internal high-voltage current source connected to
the V
str
pin. When V
CC
reaches 12V, the internal high-voltage current source
is disabled and 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™.
No Connection.
Start-up.
This pin is connected directly to the high-voltage DC link. At start-up,
the internal high-voltage current source supplies internal bias and charges the
external capacitor connected to the V
CC
pin. Once V
CC
reaches 12V, the in-
ternal current source is disabled.

Absolute Maximum Ratings
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The
device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables
are not guaranteed at the absolute maximum ratings. T
