TPS53311 Overview
The TPS53311 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 RDS(on) and TI Proprietary SmoothPWM™ skip mode of operation, it enables 95.5% peak efficiency, and over 90% efficiency at loads as light as 100 mA. It requires only two 22-µF ceramic output capacitors for a power-dense, 3-A solution.
