3 Description
The TPS55287-Q1 is a synchronous buck-boost
converter that is optimized for converting battery
voltage or adapter voltage into power supply rails.
The TPS55287-Q1 integrates four MOSFET switches
providing a compact solution for USB Power Delivery
(USB PD) application.
The TPS55287-Q1 has up to 36V input voltage
capability. Through the I2C interface, the output
voltage of the TPS55287-Q1 can be programmed
from 0.8V to 22V with 10mV step. When working in
boost mode, it can deliver 35W from a 12V input
voltage. It is capable of delivering 25W from 9V input
voltage.
The TPS55287-Q1 employs an average currentmode
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-Q1 also provides optional spread
spectrum to minimize peak EMI.
The TPS55287-Q1 offers output over-voltage
protection, average inductor current limit, cycle-bycycle
peak current limit and output short circuit
protection. The TPS55287-Q1 also ensures safe
operating with optional output current limit and hiccupmode
protection in sustained overload conditions.
The TPS55287-Q1 can use a small inductor and
small capacitors with high switching frequency. It is
available in a 3.0mm × 5.0mm QFN package.
