TPS53311 is a fully integrated synchronous buck regulator using the TI’s proprietary SmoothPMW™ voltage mode control. It is designed for 3.3-V and 5-V step-downs where system size is at a premium, and where performance and opTImized component lists are mandatory.
The TPS53311 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 over-temperature 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 6.0 V, and output voltage is adjustable from 0.
