Description for the TPS65263-Q1

The TPS65263-Q1 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 I 2C-controlled 7 bits VID. The VID voltage transition slew rate is programmable with 3-bits control through I 2C bus to optimize overshoot/undershoot during VID voltage transition.

Each buck in TPS65263-Q1 can be I 2C controlled for enabling/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.

The TPS65263-Q1 features overvoltage, overcurrent, short-circuit, and overtemperature protection.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
