Description

The NCP1402 series are monolithic micropower step-up DC to DC converter that are specially 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 0.3 V. With only three external components, this series allow a simple means to implement highly efficient converters that are capable of up to 200 mA of output current at Vin= 2.0 V, VOUT= 3.0 V.Each device consists of an on-chip PFM (Pulse Frequency Modulation) oscillator, PFM controller, PFM comparator, soft-start, voltage reference, feedback resistors, 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 NCP1402 device series are available in the Thin SOT-23-5 package with five standard regulated output voltages. Additional voltages that range from 1.8 V to 5.0 V in 100 mV steps can be manufactured.
