LTC3407-3
Dual Synchronous,
1.8V/0.8A and 3.3V/0.8A
2.25MHz Step-Down DC/DC Regulator
DESCRIPTION
The LTC
®
3407-3 is a dual, constant frequency, synchro-
nous step down DC/DC converter. Intended for low power
applications, it operates from 3.3V to 5.5V input voltage
range and has a constant 2.25MHz switching frequency,
allowing the use of tiny, low cost capacitors and inductors
with a profile ≤1.0mm. Internal synchronous 0.35Ω, 1.2A
power switches provide high efficiency without the need
for external Schottky diodes.
A user selectable mode input is provided to allow the user
to trade-off noise ripple for low power efficiency. Burst
Mode
®
operation provides high efficiency at light loads,
while pulse-skipping mode provides low noise ripple 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
40μA. In shutdown, the device draws <1μA.
