Description
The GAM13231001 is a compact, high efficiency, and low
voltage step-up DC/DC converter including an error
amplifier, ramp generator, comparator, switch pass
element and driver in which providing a stable and
high efficient operation over a wide range of load
currents. It operates in stable waveforms without
external compensation.
The low start-up input voltage below 1.1V. The high
switching rate minimized the size of external
components. Besides, the 25µA low quiescent
current together with high efficiency maintains long
battery lifetime.
