Description
The AP3983B/C/D family of power switchers is for power supplies with better conversion efficiency to easily meet energy star 6.0 and CoC tie 2 norms. , better voltage & current accuracy of ±5% max, and improved protection functions as OVP/OTP. Typical applications include charger, adapter for ADSL and home appliance power supply. This family regulates the output voltage and current in the primary side by piece-wise Pulse Frequency Modulation (p-PFM) in discontinuous conduction mode.
