Description
The YF3141 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. The output
voltage is set with two external resistors.
The YF3141 is available in the industry
standard SOT-23-6 power packages.
