This user guide supports the 16W evaluation board for ATX standby using FSB127H. It
should be used in conjunction with the FSB127H datasheet as well as Fairchild’s
application notes and technical support team. Please visit Fairchild’s website at

1. Overview
The highly integrated FSB-series consists of an integrated Current Mode Pulse Width
Modulator (PWM) and an avalanche-rugged 700V SenseFET. It is specifically designed
for high-performance offline Switch Mode Power Supplies (SMPS) with minimal
external components.
Compared with a discrete MOSFET and controller or RCC switching converter solution,
the FSB-series reduces total component count, design size, and weight while increasing
efficiency, productivity, and system reliability. These devices provide a basic platform
for the design of cost-effective flyback converters, as in PC auxiliary power supplies.
