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 0.8V 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= 2.0V, 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 5.0V in 100 mV steps can be manufactured.
Features
● Extremely Low Start-Up Voltage of 0.8 V
● Operation Down to Less than 0.3 V
● High Efficiency 85% (Vin = 2.0 V, VOUT = 3.0 V, 70 mA)
● Low Operating Current of 30 μA (VOUT = 1.9V)
● Output Voltage Accuracy ±2.5%
● Low Converter Ripple with Typical 30 mV
● Only Three External Components Are Required
● Chip Enable Power Down Capability for Extended Battery Life
● Micro Miniature Thin SOT-23-5 Packages
Typical Applications
● Cellular Telephones
● Pagers
