Notebook PC power adapter design

Products and reference designs

Block diagram

Our integrated circuits and reference designs help you create notebook personal computer (PC) power adapter designs with high-power density and higher efficiency to meet Energy Star® standards at a competitive cost.

Modern notebook PC power adapter designs often require:

Lower standby power and leakage current.
Protection for voltage, current and short circuit.
Wider input voltage range with low total harmonic distortion (THD) throughout load and line.
