3 Description
The TPS55287 is a synchronous buck-boost
converter that is optimized for converting battery
voltage or adapter voltage into power supply rails.
The TPS55287 integrates four MOSFET switches,
providing a compact solution for USB power delivery
(USB PD) application.
The TPS55287 has up to 36V input voltage capability.
Through the I2C interface, the output voltage of the
TPS55287 can be programmed from 0.8V to 22V with
10mV step. When working in boost mode, the device
can deliver 35W from a 12V input. It is capable of
delivering 25W from 9V input voltage.
The TPS55287 employs an average current-mode
control scheme. The switching frequency is
programmable from 200kHz to 2.2MHz by an external
resistor and can be synchronized to an external
clock. The TPS55287 also provides optional spread
spectrum to minimize peak EMI.
The TPS55287 offers output overvoltage protection,
average inductor current limit, cycle-by-cycle peak
current limit, and output short circuit protection.
The TPS55287 also makes sure it safely operates
with optional output current limit and hiccup-mode
protection in sustained overload conditions.
The TPS55287 can use a small inductor and
small capacitors with high switching frequency. It is
available in a 3.0mm × 5.0mm QFN package.
