description
thetps62200is high efficiency synchronous,
pwm step-down dc/dc converters working
under an input voltage range from 2.5v to 5.5v.
this feature makes thetps62200suitable for
single li-lon battery-powered applications. 100%
duty cycle capability extends battery life in
portable devices, while the quiescent current is
50
μ
a with no load, and drops to < 1
μ
a in
shutdown.
the internal synchronous switch is desired to
increase efficiency without an external schottky
diode. the 1.2 mhz fixed switching frequency
allows the using of tiny, low profile inductors and
ceramic capacitors, which minimized overall
solution footprint.
the tps62200 converters are available in the
industry standard sot-23-5 power packages (or
upon request).
