Supply TI Step Down Converter, Supply TI TPS65250RHAT Synchronous Triple Buck Converter

Shenzhen Mingjiada Electronics Co., Ltd.——Long Term Supply TI (TPS65250RHAT) 4.5V to 18V Input, High Current, Synchronous Step Down Three Buck Converter.

TPS65250RHAT——Product Informations:
Part Number: TPS65250RHAT
Package: VQFN-40
Type: Synchronous Triple Buck Converter
Product Details: TPS65250RHAT——4.5V to 18V, 3A/2A/2A output, synchronous triple buck converter.

TPS65250RHAT features three synchronous wide input range high efficiency buck converters. TPS65250RHAT is designed to simplify its application while giving the designer the option to optimize their usage according to the target application.

TPS65250RHAT converters can operate in 5-, 9-, 12- and 15-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.

The switching frequency of the TPS65250RHAT converters can either be set with an external resistor connected to ROSC pin or can be synchronized to an external clock connected to SYNC pin if needed. The switching regulators are designed to operate from 300 kHz to 2.2 MHz.

TPS65250RHAT features a unique storage and release circuitry for dying gasp mode. The storage capacitor is separated from input capacitor during normal operation.

TPS65250RHAT continuously monitors the input voltage. Once the input voltage drops below a release voltage of 10.5 V, the circuit tries to transfer charge from storage capacitor to the input capacitor keeping the input voltage closer to release value for as long as possible.

TPS65250RHAT features a supervisor circuit that monitors Buck 1 and Buck 3 output voltage and generates an internal power good (PG) signal. The PGOOD pin is asserted once sequencing is done, all PG signals are reported and a selectable end of reset time lapses. The polarity of the PGOOD signal is active high.

TPS65250RHAT 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.

TPS65250RHAT is packaged in a small, thermally efficient QFN RHA40 package.
