Description
This highly integrated PWM controller provides several
features to enhance the performance of low-power
flyback converters. The proprietary topology enables
most simplified circuit design especially for battery
charger applications. A low-cost, smaller, and lighter
charger results when compared to a conventional
design or a linear transformer. The startup current is
only 10μA, which allows large startup resistance for
further power saving.
To minimize the standby-power consumption, the
proprietary green-mode function provides off-time
modulation to linearly decrease PWM frequency under
light-load conditions. This green-mode function assists
the power supply in meeting power conservation
requirements.
By using FSEZ1216B, a charger can be implemented
with few external components and minimized cost. A
typical output CV/CC characteristic envelope is shown
in Figure 1.
FSEZ1216B series controllers are available in an 8-pin
DIP package.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
