The TPS61033-Q1 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 supplies. The TPS61033-Q1 has a 5.5-A (typical) valley switch current limit and TPS610333-Q1 has 1.85-A (typical) valley switch current limit over full temperature range.

The TPS61033-Q1 uses adaptive, constant on-time valley-current-control topology to regulate the output voltage and operates at a 2.4-MHz switching frequency. There are two optional modes at light load by configuring the MODE pin: auto PFM mode and forced PWM. These modes balance the efficiency and noise immunity in light load. The TPS61033-Q1 consumes a 20 µA quiescent current from V IN at light load condition. During shutdown, the TPS61033-Q1 is completely disconnected from the input power and only consumes a 0.1 µA current to achieve long battery life. The TPS61033-Q1 has a 5.75-V output overvoltage protection, an output short circuit protection, and thermal shutdown protection.

The TPS61033-Q1 offers a small solution size with a 2.1mm × 1.6mm SOT-5X3 (8) package and a minimum amount of external components.
