NCP1400A

100 mA, Fixed Frequency

PWM Step−Up Micropower

Switching Regulator

The NCP1400A series are micropower step−up DC to DC

converters that are specifically designed for powering portable

equipment from one or two cell battery packs. These devices are

designed to start−up with a cell voltage of 0.8 V and operate down to

less than 0.2 V. With only four external components, this series allows

a simple means to implement highly efficient converters that are

capable of up to 100 mA of output current.

Each device consists of an on−chip fixed frequency oscillator, pulse

width modulation controller, phase compensated error amplifier that

ensures converter stability with discontinuous mode operation,

soft−start, voltage reference, driver, and power MOSFET switch with

current limit protection. Additionally, a chip enable feature is provided

to power down the converter for extended battery life.

The NCP1400A device series are available in the Thin SOT23−5

package with seven standard regulated output voltages. Additional

voltages that range from 1.8 V to 4.9 V in 100 mV steps can be

manufactured.
