Description
The FAN302HLMY_F117 advanced PWM controller
significantly simplifies isolated power supply design that
requires CC regulation of the output. The output current
is precisely estimated with information in the primary
side of the transformer and controlled with an internal
compensation circuit. This removes the output current
sensing loss and eliminates all external Control Circuitry
(CC). The Green-Mode function, with an extremely low
operating current (200 µA) in Burst Mode, maximizes
the light-load efficiency, enabling conformance to
worldwide Standby Mode efficiency guidelines.
Integrated protections include two-level pulse-by-pulse
current limit, Over-Voltage Protection (OVP), brownout
protection, and Over-Temperature Protection (OTP).
Compared with a conventional approach using an
external control circuit in the secondary side for CC
regulation, the FAN302HLMY_F117 can reduce total
cost, component count, size, and weight; while
simultaneously increasing efficiency, productivity, and
system reliability.
