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 FSEZ1317WA enables precise
CC regulation and simplified circuit design 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 provides off-time modulation to
linearly decrease PWM frequency under light-load
conditions. Green mode assists the power supply in
meeting power conservation requirements.
By using the FSEZ1317WA, 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 transformers and RCC SMPS
