NCP1400A
100 mA, Fixed Frequency
PWM Step鈭扷p Micropower
Switching Regulator
The NCP1400A series are micropower step鈭抲p 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鈭抲p 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鈭抍hip fixed frequency oscillator, pulse
width modulation controller, phase compensated error amplifier that
ensures converter stability with discontinuous mode operation,
soft鈭抯tart, 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鈭?
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.
