This third-generation Primary-Side-Regulation (PSR)
and highly integrated PWM controller provides several
features to enhance the performance of low-power
flyback converters. The proprietary topology,
TRUECURRENT ? , of FAN103 enables precise CC
regulation and simplified circuit for battery charger
applications. A low-cost, smaller and lighter charger
results as compared to a conventional design or a linear
transformer.
To minimize standby power consumption, the
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 the power conservation requirement.
By using the FAN103, a charger can be implemented
with few external components and minimized cost. A
typical output CV/CC characteristic envelope is shown
in Figure 1.
Applications

Battery chargers for cellular phones, cordless
phones, PDA, digital cameras, power tools, etc.
Replaces linear transformer and RCC SMPS
