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.
