Diodes' AP3983 switcher family regulates the output voltage and current on the primary side by piece-wise pulse frequency modulation (p-PFM) in discontinuous conduction mode with an operating frequency up to 80 kHz. The AP3983 family has built-in fixed cable voltage compensation. The AP3983 is offered in a SO-7 package, delivering output powers up to 10 W, and the PDIP-7 package, delivering powers up to 20 W.
