The Texas Instruments TPS65232A0RHAR is a versatile Power Management IC (PMIC) featuring a triple buck topology. It is designed to handle a wide input supply voltage range from 10.8 V to 22 V, making it suitable for demanding applications.
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 provides two adjustable step-down converters with integrated switching FETs, supporting an input voltage of 4.75 V to 5.5 V and an output voltage range of 0.9 V to 3.3 V, with a maximum output current of 3 A per converter and a 1 MHz switching frequency.
Key features include adjustable current limit, enable functionality, overcurrent protection, and soft-start for controlled power-up sequences. The device also incorporates pull-up current sources on buck enable pins for accurate start-up timing and preset default overcurrent protection on all rails. Thermal shutdown is included to protect the device during excessive power dissipation.
The TPS65232A0RHAR is housed in a 40-VQFN (6x6 mm) package, suitable for surface mounting. Its applications include xDSL and cable modems, wireless access points, set-top boxes (STB), DTVs, DVDs, and home gateways.
