Description

General part information

TPS65263-1Q1 Series

The TPS65263-1Q1 incorporates triple-synchronous buck converters with 4.0- to 18-V wide input voltage. The converter with constant frequency peak current mode is designed to simplify its application while giving designers options to optimize the system according to targeted applications. The switching frequency of the converters is adjustable from 200 kHz to 2.3 MHz with an external resistor. 180° out-of-phase operation between buck1 and buck2, buck3 (buck2 and buck3 run in phase) minimizes the input filter requirements.

The initial start-up voltage of each buck can be set with external feedback resistors. The output voltage of buck2 can be dynamically scaled from 0.68 to 1.95 V in 10-mV steps with I2C-controlled 7 bits VID. The VID voltage transition slew rate is programmable with 3-bits control through I2C bus to optimize overshoot, undershoot during VID voltage transition.

Each buck in TPS65263-1Q1 can be I2C controlled for enabling and disabling output voltage, setting the pulse skipping mode (PSM) or forced continuous current (FCC) mode at light load condition and reading the power-good status, overcurrent warning, and die temperature warning.
