Description
The FSDM311A consists of an integrated Pulse Width
Modulator (PWM) and SenseFET, and is specifically
designed for high-performance, off-line, Switch-Mode
Power
components. This device is an integrated high-voltage
power switching regulator that combines a VDMOS
SenseFET with a voltage-mode PWM control block. The
integrated PWM controller features include a fixed
oscillator, Under-Voltage Lockout (UVLO) protection,
Leading-Edge Blanking (LEB), an optimized gate turn-
on/turn-off driver, Thermal Shutdown (TSD) protection,
and
sources for loop compensation and fault protection
circuitry. When compared to a discrete MOSFET and
controller or RCC switching converter solution, the
FSDM311A device reduces total component count and
design size and weight, while increasing efficiency,
productivity, and system reliability. This device provides
a basic platform that is well suited for the design of
cost-effective flyback converters.
