TPS53321 Overview
The TPS53321 device provides a fully integrated 3-V to 5-V VIN integrated synchronous FET converter solution with 16 total ponents in 200 mm2 of PCB area. Due to the low ON-resistance and TI's Proprietary SmoothPWM™ skip mode of operation, it enables 96% peak efficiency and over 90% efficiency at loads as light as 100 mA. It requires only two 22µF ceramic output capacitors for a power dense 5-A solution.
