The TPSM852892 is a buck-boost module that is optimized for converting battery voltage or adapter voltage into power supply rails. The TPSM852892 integrates four MOSFET switches and one power inductor providing a compact solution for a variety of applications. The TPSM852892 has up to 36V input voltage capability. When working in boost mode, the TPSM852892 can deliver 50W from a 12V input.
The TPSM852892 employs an average current-mode control scheme. The switching frequency is programmable from 400kHz to 1MHz by an external resistor and can be synchronized to an external clock. The TPSM852892 also provides optional spread spectrum to minimize peak EMI.
The TPSM852892 offers output over-voltage protection, average inductor current limit, cycle-by-cycle peak current limit, output short circuit protection. The TPSM852892 also specifies safe operating with optional output current limit and hiccup-mode protection in sustained overload conditions.
The TPSM852892 is designed with ZEN 2 switcher technology to quickly and easily implement a low-EMI design and offers a small solution size with 7.5mm × 7.7mm QFN package.
