Chapter 1. Summary
1.1 General Description
Based on Primary Side Regulation (PSR) Flyback
topology, the 10W Charger EV1 Evaluation board is
designed as an MP-form-factor, cost-effective, optimal
efficiency, charger reference design to facilitate further
customization by users. AP3983R PSR Switcher, co-
packaged a 700V N-MOSFE and a PSR control die, along
with APR3415B Synchronous Rectification (SR) Switcher,
co-packaged a MOS die with an SR controller, enable
high-efficiency and small size form-factor 10W charger
designs. The overall efficiency of the evaluation board
can meet DOE VI and CoC Tier 2 energy efficiency
requirements.

4.2 Quick Start Guide Before Connection
1. The evaluation board is preset at 5V/2A from output + & -
2. Ensure that the AC source is switched OFF or disconnected before doing connection.
3. Connect the AC line wires of power supply to “L and N” on the left side of the board.
4. Turn on the AC main switch.
5. Measure Red & Black wires to ensure correct output voltages at 5V respectively.
