OPERATION
The MP2101 is a fixed-frequency 1.6MHz,
800mA current mode PWM step-down switcher
with a 200mA low dropout (LDO) linear
regulator. The MP2101 is optimized for low
voltage, Li-Ion battery powered applications
where high efficiency and small size are critical.
The MP2101 uses an external resistor divider to
set both the switcher and LDO output voltage
from 0.6V to 6V.
