The TPS552872-Q1 is a
synchronous buck-boost converter that is optimized for converting battery voltage or
adapter voltage into power supply rails. The TPS552872-Q1 integrates four MOSFET switches providing a compact solution
for a variety of applications. The TPS552872-Q1 has up
to 36V input voltage capability. When working in boost mode, the TPS552872-Q1 can deliver 30 W from a 12-V input. It is
capable of delivering 25 W from 9-V input voltage.
The TPS552872-Q1
employs an average current-mode 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-Q1 also provides optional
spread spectrum to minimize peak EMI.
The TPS552872-Q1
offers output over-voltage protection, average inductor current
limit, cycle-by-cycle peak current limit, output short circuit
protection. The TPS552872-Q1 also
ensures safe operating with optional output current limit and
hiccup-mode protection in sustained overload conditions.
The TPS552872-Q1 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.
