The TPS552882-Q1 is a synchronous four-switch
buck-boost converter capable of regulating the output voltage at, above, or below the input
voltage. The TPS552882-Q1 operates over 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-Q1 integrates two 16-A MOSFETs of
the boost leg to balance the solution size and efficiency. The
TPS552882-Q1 uses external resistor divider to set the output
voltage with 1.2-V intenral reference voltage. The TPS552882-Q1 is
capable of delivering 100 W from 12-V input voltage.
The TPS552882-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 TPS552882-Q1 also
provides optional spread spectrum to minimize peak EMI.
The TPS552882-Q1 offers output overvoltage
protection, average inductor current limit, cycle-by-cycle peak
current limit, and output short circuit protection. The TPS552882-Q1
also ensures safe operating with optional output current limit and
hiccup-mode protection in sustained overload conditions.
The TPS552882-Q1 can use a small inductor and
small capacitors with high switching frequency. It is available in a 4.0-mm × 3.5-mm QFN
package.
