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, copackaged 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.
