New high-frequency switch-mode Li-Ion battery charger simplifies constant current control in quick-charge portables. The ADP2291 is a constant-current/constant-voltage linear charger for a single cell lithium ion battery, requiring just a few components to provide a simple and safe charging system that operates from a wide 4.5V to 12V input voltage range. The industry’s highest end-of-voltage accuracy levels are achieved to within ±0.4% at 25ºC, ±0.6% at 5ºC to 55ºC and ±0.7% at 0ºC to 85ºC.
