FAN5365 Datasheet 6mhz Digitally Programmable Regulator

Manufacturer: Fairchild (now onsemi)

Overview: FAN5365 — 1A / 0.8A, 6MHz Digitally Programmable Regulator August 2011 FAN5365 1A / 0.

General Description

The FAN5365 is a high-frequency, ultra-fast transient response, synchronous step-down, DC-DC converter optimized for low-power applications using small, low-cost inductors and capacitors.

The FAN5365 supports up to 800mA or 1A load current.

The FAN5365 is ideal for mobile phones and similar portable applications powered by a single-cell Lithium-Ion battery.
