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 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.
