Description

General part information

TPS65253 Series

The TPS65253 features two synchronous wide input range high efficiency buck converters. The converters are designed to simplify product application while giving designers the options to optimize their usage according to the target application.

The converters can operate in 5-, 9- and 12-V systems and have integrated power transistors. The output voltage can be set externally using a resistor divider to any value between 0.8 V and the input supply minus 1 V. Each converter features an enable pin that allows a delayed start-up for sequencing purposes, soft-start pin that allows adjustable soft-start time by choosing the soft-start capacitor, and a current limit (RLIMx) pin that enables designer to adjust current limit by selecting an external resistor and optimize the choice of inductor. The CMP pin allows optimizing transient versus dc accuracy response with a simple RC compensation.

The switching frequency of the converters is set by an external resistor connected to ROSCpin. The switching regulators are designed to operate from 300 kHz to 1.2 MHz. The converters operate with 180° phase between then to minimize the input filter requirements.
