TPS65232A2DCA

The Texas Instruments TPS65232A2DCA is a versatile Power Management Integrated Circuit (PMIC) designed for demanding applications. It features a wide input supply voltage range from 10.8 V to 22 V, accommodating diverse power sources.

This PMIC includes one adjustable PWM buck controller with an output voltage range of 3.3 V to 6.1 V, operating at a 500 kHz switching frequency. Additionally, it incorporates two adjustable step-down converters with integrated switching FETs, supporting an input voltage range of 4.75 V to 5.5 V and providing an output voltage from 0.9 V to 3.3 V with a 3 A output current and a 1 MHz switching frequency.

Key features include adjustable current limit, enable functionality, overcurrent protection, and soft-start capabilities. The device also offers pull-up current sources on buck enable pins for accurate start-up timing control and preset default overcurrent protection on all rails. Thermal shutdown is integrated to protect the device during excessive power dissipation.

The TPS65232A2DCA is housed in a thermally enhanced 48-HTSSOP package, measuring 12.5 mm x 8.1 mm, ensuring efficient heat management. Its applications include xDSL and cable modems, wireless access points, set-top boxes (STB), DTVs, DVDs, and home gateways.
