Description
This highly integrated PWM controller, FAN301,
provides features to enhance the performance of low-
power flyback converters. The proprietary topology
enables simplified circuit design for battery charger
applications. A low-cost, smaller, and lighter charger is
the result, compared to a conventional design or a
linear transformer.
To minimize standby power consumption, a proprietary
green-mode function provides off-time modulation to
linearly decrease PWM frequency under light-load
conditions. This green mode assists the power supply in
meeting power conservation requirements.
By using FAN301, a charger can be implemented with
fewer external components and minimized cost. A
typical output CV/CC characteristic envelope is shown
in Figure 1.

Description
Current sense. Connected to a current-sense resistor for peak-current-mode control in CV
mode. The current-sense signal is also provided for output-current regulation in CC mode.
The totem-pole output driver to drive the power MOSFET.
Power supply
Feedback. The VS pin provides feedback information for output-current regulation in CC mode.
Power ground
Feedback. The FB pin provides feedback information to the internal PWM comparator. This
feedback is used to control the duty cycle.
No connection
For startup. This pin is pulled HIGH to the line input or bulk capacitor via resistors.
