This document describes a 3.5W power supply using an FSEZ1317AMY device. This
power supply is targeted for mobile phone battery chargers for a 30mW solution with
high efficiency.
The controller used on the board is Fairchild Semiconductor’s FSEZ1317AMY. This
third-generation Primary-Side-Regulation (PSR) PWM controller with integrated
MOSFET and improved EMI performance provides several features to enhance the
performance of low-power flyback converters. The proprietary TRUECURRENT®
technology enables precise Constant Current (CC) regulation and simplified circuit
design for battery-charger applications. The result is a lower-cost, smaller, and lighter
charger compared to conventional designs or a linear transformer. To minimize standby
power consumption (30mW at 265V
modulation to linearly decrease PWM frequency under light-load conditions. Green
Mode assists the power supply in meeting power conservation requirements. By using the
FSEZ1317A, a charger can be implemented with few external components and
minimized cost. A typical output CV/CC (Constant Voltage / Constant Current)
characteristic envelope is shown in Figure 23 and Figure 24.
