3 Description

The TPS552892 is a synchronous buck-boost

converter that is optimized for converting battery

voltage or adapter voltage into power supply rails.

The TPS552892 integrates four MOSFET switches

providing a compact solution for a variety of

applications. The TPS552892 has up to 36V input

voltage capability. When working in boost mode, the

TPS552892 can deliver 60 W from a 12-V input. It is

capable of delivering 45 W from 9-V input voltage.

The TPS552892 employs an average currentmode

control scheme. The switching frequency is

programmable from 200 kHz to 2.2 MHz by an

external resistor and can be synchronized to an

external clock. The TPS552892 also provides optional

spread spectrum to minimize peak EMI.

The TPS552892 offers output over-voltage protection,

average inductor current limit, cycle-by-cycle peak

current limit, output short circuit protection. The

TPS552892 also ensures safe operating with optional

output current limit and hiccup-mode protection in

sustained overload conditions.

The TPS552892 can use a small inductor and

small capacitors with high switching frequency. The

TPS552892 is available in a 3.0-mm × 5.0-mm QFN

package.
