6A output current buck-boost module with integrated inductor

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.
