DESCRIPTION
Monolithic Dual Tracking
3.5A Step-Down
Switching Regulator
The LT3692 is a dual current mode PWM step-down
DC/DCconverterwithtwointernal3.8Aswitches.Indepen-
dentinputvoltage,shutdown,feedback,soft-start,current
limit and comparator pins for each channel simplify com-
plex power supply tracking and sequencing requirements.
To optimize efficiency and component size, both convert-
ers have a programmable maximum current limit and are
synchronized to either a common external clock input,
or a resistor settable fixed 250kHz to 2.25MHz internal
oscillator. A frequency divider is provided for channel 1
to further optimize component size. At all frequencies, a
180° phase relationship between channels is maintained,
reducingvoltagerippleandcomponentsize.Aclockoutput
is available for synchronizing multiple regulators.
Minimum input to output voltage ratios are improved by
allowingtheswitchtostayonthroughmultipleclockcycles
onlyswitchingoffwhentheboostcapacitorneedsrecharg-
ing. Independent channel operation can be programmed
using the SHDN pin. Disabling both converters reduces
the total quiescent to <10A.
