Description
The FSDM0465RB 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 which
combines a rugged avalanche, SenseFET with a current mode
PWM control block. The PWM controller includes 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, the PWM/
FSDMRB can reduce total cost, component count, size and
weigh, while simultaneously increasing efficiency, productivity,
and system reliability. This device provides a basic platform
well suited for cost-effective designs of flyback converters.

Notes:
1. Typical continuous power in a non-ventilated enclosed
adapter measured at 50
°
C ambient.
2. Maximum practical continuous power in an open frame
design at 50
°
C ambient.
3. 230 VAC or 100/115 VAC with doubler.
4. The junction temperature can limit the maximum output
power.
