Description

The FP6366 is a high efficiency, low-noise, DC-DC

step-down pulse width modulated (PWM) converter

that goes automatically into PFM mode at light load

to improve efficiency.

It is ideally suitable for

systems powered from a 1-cell Li-ion battery or from

a 2 to 3-cell NiCd, NiMH or alkaline battery.

The

100% duty cycle feature provides low dropout

operation, extending battery life in portable systems.

Switch frequency is internally set at 1.5MHz, allowing

use of small surface mount inductors and capacitors.

The internal synchronous switch increases efficiency

and eliminates the need for external Schottky diode.

Shutdown mode places the device in standby,

reducing quiescent supply current to less than 1µA.

The FP6366 is available in a small SOT-23-5

package.
