AEC-Q100 qualified:  
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.  
– Device temperature grade 1: –40°C to +125°C  
ambient operating temperature range  
Wide input and output voltage range  
– Wide input voltage range: 2.7 V to 36 V  
– Wide output voltage range: 0.8 V to 22 V  
High efficiency over entire load range  
– 97% efficiency at VIN = 12 V, VOUT = 20 V and  
IOUT = 3 A  
Avoid frequency interference and crosstalk  
– Optional clock synchronization  
– Programmable switching frequency from 200  
kHz to 2.2 MHz  
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.

EMI mitigation  
– Optional programmable spread spectrum  
– Lead-less package  
Rich protection features  
– Output overvoltage protection  
– Hiccup mode for output short-circuit protection  
– Thermal shutdown protection  
– Programmable average inductor current limit up  
to 16 A  
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.  
•
•
Small solution size  
– Maximum switching frequency up to 2.2 MHz  
– 4.0-mm × 3.5-mm HotRod™ QFN package with  
wettable flank option  
Adjustable output voltage compensation for  
voltage droop over the cable  
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.  
•
•
Programmable PFM and FPWM mode at light load  
Programmable output current limit by sensing  
resistor  
±1% reference voltage accuracy  
Fixed 4-ms soft-start time
