The TPS552882 is a synchronous
four-switch buck-boost converter capable of regulating the output voltage at, above,
or below the input voltage. The TPS552882 operates over a 2.7-V to 36-V wide input
voltage and is capable of outputing 0.8-V to 22-V voltage to support a variety of
applications.
The TPS552882 integrates two 16-A
MOSFETs of the boost leg to balance the solution size and efficiency. The TPS552882
uses an external resistor divider to set the output voltage with 1.2V internal
reference voltage. The TPS552882 is capable of delivering 100 W from 12-V input
voltage.
The TPS552882 employs 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
TPS552882 also provides optional spread spectrum to minimize peak EMI.
The TPS552882 offers output
over-voltage protection, average inductor current limit, cycle-by-cycle peak current
limit and output short circuit protection. The TPS552882 also ensures safe operating
with optional output current limit and hiccup-mode protection in sustained overload
conditions.
The TPS552882 can use a small inductor
and small capacitors with high switching frequency. It is available in a 4.0-mm ×
3.5-mm HotRod QFN package.
