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 V IN 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.
