Dual channel synchronous step-down switcher, this power management IC features integrated FETs for efficient power conversion. Delivering up to 4A on one output and 2A on the second, it operates from a 4.5V to 18V input range with adjustable output voltages from 760mV to 7V. The device offers a 1.2mA quiescent current and is housed in a lead-free, surface-mount QFN package, suitable for operation between -40°C and 85°C.
