The LTC?407 is a dual, constant frequency, synchronous
step down DC/DC converter. Intended for low power applications,
it operates from 2.5V to 5.5V input voltage
range and has a constant 1.5MHz switching frequency,
allowing the use of tiny, low cost capacitors and inductors
2mm or less in height. Each output voltage is adjustable
from 0.6V to 5V. Internal synchronous 0.35? 1A power
switches provide high effi ciency without the need for
external Schottky diodes.
A user selectable mode input is provided to allow the user
to trade-off ripple noise for low power effi ciency. Burst
Mode?operation provides high effi ciency at light loads,
while pulse-skipping mode provides low ripple noise at
light loads.
To further maximize battery life, the P-channel MOSFETs
are turned on continuously in dropout (100% duty cycle),
and both channels draw a total quiescent current of only
40霢. In shutdown, the device draws <1霢.
