The TPSM81033 is a synchronous boost power module and operates from an input voltage supply range up to 5.5V with 5.5A (typical) valley switch current limit. The TPSM81033 operates at 2.4MHz 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 TPSM81033 consumes an 20μA quiescent current from VIN at light load condition. During shutdown, the TPSM81033 is completely disconnected from the input power and only consumes a 0.1μA 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.

The TPSM81033 versions in the VCD package uses MagPack packaging technology to deliver the highest-performance power module design. Leveraging our proprietary integrated-magnetics packaging technology, power modules with MagPack (magnetics in package) packaging technology deliver industry-leading power density, high efficiency, good thermal performance, ease of use, and reduced EMI emissions.
