NCP1402
200 mA, PFM Step-Up Micropower Switching Regulator
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 startup 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 po...
