Available in 5mm × 5mm QFN Package The LTC®3708 is a dual, 2-phase synchronous step-down
switching regulator with output voltage up/down tracking
capability. The IC allows either coincident or ratiometric
tracking. Multiple LTC3708s can be daisy-chained in applications requiring more than two voltages to be tracked.
Power supply sequencing is accomplished using an external soft-start timing capacitor. …
