8.1 Overview

The TPS61033 is a fully-integrated synchronous boost converter and operates from an input voltage supply range from 1.8 V to 5.5 V with 5.5-A (typical) valley switch current limit. The TPS61033 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 TPS61033 consumes an 20-μA quiescent current from VIN at light load condition. During shutdown, the TPS61033 is completely disconnected from the input power and only consumes a 0.1-μA current to achieve long battery life. During PWM operation, the converter uses adaptive constant on-time valley current mode control scheme to achieve excellent line regulation and load regulation and allows the use of a small inductor and ceramic capacitors. Internal loop compensation simplifies the design process while minimizing the number of external components.
