DESCRIPTION
The LTC®3417A-2 is a dual constant frequency, synchronous step-down DC/DC
converter. Intended for medium power applications, it operates from a 2.25V to
5.5V input voltage range and has a constant programmable switching frequency,
allowing the use of tiny, low cost capacitors and inductors 2mm or less in
height. Each output voltage is adjustable from 0.8V to 5V. Internal
synchronous, low RDS(ON) power switches provide high efficiency without the
need for external Schottky diodes.
A user selectable mode input allows the user to trade off ripple voltage for
light load efficiency. Burst Mode operation provides high efficiency at light
loads, while Pulse Skip mode provides low ripple noise at light loads. A phase
mode pin allows the second channel to operate in-phase or 180° out-of-phase
with respect to channel 1. Out-of-phase operation produces lower RMS current
on VIN and thus lower stress on the input capacitor.
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 100μA. In shutdown, the device draws <1μA.
