3 Description

The TPS61033X is a synchronous boost converter.

The device provides a power supply solution for

portable equipment and smart devices powered

by various batteries and other power supply. The

TPS61033 has 5.5-A (typical) valley switch current

limit and TPS610333 has 1.85-A (typical) valley

switch current limit over full temperature range.

The TPS61033X uses adaptive constant on-time

valley-current-control topology to regulate the output

voltage and operates at 2.4-MHz switching frequency.

There are two optional modes at light load by

configuring the MODE pin: auto PFM mode and

forced PWM to balance the efficiency and noise

immunity in light load. The TPS61033X consumes

a 20-μA quiescent current from VIN at light load

condition. During shutdown, the TPS61033X is

completely disconnected from the input power and

only consumes a 0.1-μA current to achieve long

battery life. The TPS61033X has 5.75-V output

overvoltage protection, output short circuit protection,

and thermal shutdown protection.

The TPS61033X offers a very small solution size with

2.1-mm × 1.6-mm SOT583 package and minimum

amount of external components.
