Pin # Symbol Pin Description 1 CE Chip Enable pin (1) The chip is enabled if a voltage which is equal to or greater than 0.9 V is applied (2) The chip is disabled if a voltage which is less than 0.3 V is applied (3) The chip will be enabled if it is left floating 2 OUT Output voltage mo

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
