General Description

The TPS65265 incorporates triple synchronous buck converters with 4.5-V to 17-V wide input voltage range that encompassed most intermediate bus voltage operating off 5-, 9-, 12- or 15-V power bus or battery.

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 can be adjustable from 250 kHz to 2.3 MHz with an external resistor or external clock.
