The TPS55288 is a
synchronous four-switch buck-boost converter capable of regulating
the output voltage at, above, or below the input voltage. The
TPS55288 operates over 2.7-V to 36-V wide input voltage and capable
of outputing 0.8-V to 22-V voltage to support a variety of
applications.
The TPS55288 integrates
two 16-A MOSFETs of the boost leg to balance the solution size and
efficiency. With the programmable output voltage and output current
limit through I2C interface, the TPS55288 is fully
compliant to the USB PD specification. The TPS55288 is capable of
delivering 100 W from 12-V input voltage.
The TPS55288 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 TPS55288 also provides
optional spread spectrum to minimize peak EMI.
The TPS55288 offers output over-voltage
protection, average inductor current limit, cycle-by-cycle peak
current limit and output short circuit protection. The TPS55288 also
ensures safe operating with optional output current limit and
hiccup-mode protection in sustained overload conditions.
The TPS55288 can use a small inductor and small capacitors with high switching frequency. It is available in 4.0-mm × 3.5-mm QFN package.
