The NCP1402 is a 200mA, PFM step-up micropower switching regulator from Semiconductor Components Industries. It features an extremely low startup voltage (0.8V), high efficiency (85%), low operating current (30μA), high output voltage accuracy (±2.5%), low converter ripple (typical 30mV), and requires only three external components.
The NCP1402 series are monolithic micropower step-up DC to DC converters designed for powering portable equipment from one or two cell battery packs. These devices can start up with a cell voltage of 0.8 V and operate down to less than 0.3 V, utilizing only three external components.
