TPS54494PWP
4A/2A Dual DC/DC Step-Down Controller, 4.5-18V In, 0.76-7V Out, 2 Outputs, HTSSOP
Dual-channel synchronous step-down switcher, this power management IC features integrated FETs for efficient voltage conversion. It supports adjustable output voltages from 760mV to 7V, with a maximum output current of 4A on one channel and 2A on the second. Operating from a 4.5V to 18V input, this surface-mount device is housed in a 16-HTSSOP package, measuring 5.1mm x 4.5mm x 1.05mm. The component offers a low quiescent current of 1.2mA and operates across a temperature range of -40°C to 85°C.
