Description
The FSDH0170RNB/FSDH0270RNB/FSDH0370RNB
consists of an integrated current mode Pulse Width Mod-
ulator (PWM) and an avalanche rugged 700V Sense
FET. It is specifically designed for high performance off-
line Switch Mode Power Supplies (SMPS) with minimal
external components. The integrated PWM controller
features include : a fixed oscillator with frequency mod-
ulation 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, and temperature compensated precision cur-
rent sources for loop compensation and fault protection
circuitry. Compared to a discrete MOSFET and controller
or RCC switching converter solution, the FSDH0170RNB/
FSDH0270RNB/FSDH0370RNB reduces total compo-
nent count, design size, and weight while increasing
efficiency, productivity, and system reliability. These
devices provide a basic platform that is well suited for the
design of cost-effective flyback converters, as in PC
auxiliary power supplies.
