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 startup 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.
Features
• Extremely Low Startup Voltage of 0.8 V
• Operation Down to Less than 0.2 V
• Only Four External Components for Simple Highly Efficient
Converters
• Up to 100 mA Output Current Capability
• Fixed Frequency Pulse Width Modulation Operation
• Phase Compensated Error Amplifier for Stable Converter Operation
• Chip Enable Power Down Capability for Extended Battery Life
• Pb−Free Packages are Available
Typical Applications
• Cellular Telephones
• Pagers
• Personal Digital Assistants
• Electronic Games
• Digital Cameras
• Camcorders
• Handheld Instruments
• White LED Torch Light
