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 (200µA) 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.

Description
Current Sense. This pin connects a current-sense resistor to sense the MOSFET current for
Peak-Current-Mode control for output regulation. The current-sense information is also used to
estimate the output current for CC regulation.
PWM Signal Output. This pin has an internal totem-pole output driver to drive the power
MOSFET. It is internally clamped at 15V.
Power Supply. IC operating current and MOSFET driving current are supplied through this pin.
This pin is typically connected to an external VDD capacitor.
Voltage Sense. This pin detects the output voltage information and diode current discharge
time based on the voltage of the auxiliary winding.
Ground
Feedback. Typically, an opto-coupler is connected to this pin to provide feedback information to
the internal PWM comparator. This feedback is used to control the duty cycle in CV regulation.
No Connect
High Voltage. This pin connects to the DC bus for high-voltage startup.
