3 Description
The TPS552872 is a synchronous buck-boost
converter that is optimized for converting battery
voltage or adapter voltage into power supply rails.
The TPS552872 integrates four MOSFET switches
providing a compact solution for a variety of
applications. The TPS552872 has up to 36V input
voltage capability. When working in boost mode, the
TPS552872 can deliver 30 W from a 12-V input. It is
capable of delivering 25 W from 9-V input voltage.
The TPS552872 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 TPS552872 also provides optional
spread spectrum to minimize peak EMI.
The TPS552872 offers output over-voltage protection,
average inductor current limit, cycle-by-cycle peak
current limit, output short circuit protection. The
TPS552872 also ensures safe operating with optional
output current limit and hiccup-mode protection in
sustained overload conditions.
The TPS552872 can use a small inductor and
small capacitors with high switching frequency. It is
available in a 3.0-mm × 5.0-mm QFN package.
