TPS65252的产品详情:

The TPS65252 features two synchronous wide input range high efficiency buck converters. The converters are designed to simplify its application while giving the designer the option to optimize their usage according to the target application.

The converters can operate in 5-, 9- or 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 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 COMP pin allows optimizing transient versus dc accuracy response with a simple RC compensation.

The switching frequency of the converters can be set with an external resistor connected to ROSC pin. The switching regulators are designed to operate from 300 kHz to 2.2 MHz. The converters operate with 180° phase between them to minimize the input filter requirements.

TPS65252 also features a low power mode enabled by an external signal, which allows for a reduction on the input power supplied to the system when the host processor is in stand-by (low activity) mode.

The USB switch provides up to 1-A of current as required by downstream USB devices. When the output load exceeds the current-limit threshold selected with an external resistor or a short is present, the PMU limits the output current to a safe level by switching into a constant-current mode and pulling the over current logic output low. When continuous heavy overloads and short-circuits increase the power dissipation in the switch, causing the junction temperature to rise, a thermal protection circuit shuts off the switch to allow continuous non-interrupted operation the buck converters.

The TPS65252 features a supervisor circuit that monitors both converters and provides a PGOOD signal (End of Reset) with a 256-ms timer.

TPS65252 is packaged in a small, thermally efficient 28-pin QFN package.
