NCP1400ASN50T1G

Повышающий импульсный стабилизатор, фиксированный, 800мВ-5.5В (Vin), 5В и 0.1A на выходе, TSOT-23-5.

The NCP1400ASN50T1G is a Micropower Step-up DC to DC Boost Converter that is specifically designed for powering portable equipment from one or two cell battery packs. This device is designed to start-up with a cell voltage of 0.8V and operates down to less than 0.2V. With only four external components, this series allows a simple means to implement highly efficient converters that are capable of up to 100mA 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.
