The TPS53310 provides a fully integrated 3-V to 5-V VIN integrated synchronous FET converter solution with 16 total components, in 200 mm2 of PCB area. Due to the low RDS(on) and TI's 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.

The TPS53310 features a 1.1-MHz switching frequency, SKIP mode operation support, pre-bias startup, internal softstart, output soft discharge, internal VBST switch, power good, EN/input UVLO, overcurrent, overvoltage, undervoltage and overtemperature protections and all ceramic output capacitor support. It supports supply voltage from
2.9 V to 3.5 V and conversion voltage from 2.9 V to
6 V, and output voltage is adjustable from 0.6 V to
0.84 V × VIN.

The TPS53310 is available in the 3 mm × 3 mm,
16-pin VQFN package (Green RoHs compliant and Pb free) and operates between –40°C and 85°C.

TPS53310EVM-755 — Evaluation Module for TPS53310: 2.9V to 6V, 3-A Step-Down Converter with Integrated MOSFETs

The TPS53310EVM-755 evaluation module (EVM) is a high-efficiency evaluation platform with twoTPS53310 3-A, integrated FET, step-down converters working in a Master-Slave synchronization scheme. The two outputs are 1.5 V/3 A (master) and 1.2 V/3 A (slave) from a 3.3-V or 5-V input bus. The EVM uses (...)
