Product Overview
The TPS650250 is an integrated Texas Instruments power management IC for multirail SoCs. Its power architecture includes three step-down converters, two 200 mA general-purpose LDO regulators, and one 30 mA always-on LDO rail. The DCDC outputs are positioned for system voltage, memory voltage, and processor core rails, with DCDC operating modes selectable as PowerSafe PFM at light loads, PWM at higher loads, or forced PWM.
DCDC1 supports 1600 mA output current and 97% efficiency, with default 3.3 V, 2.8 V, or adjustable operation. DCDC2 supports 800 mA and up to 95% efficiency with 1.8 V, 2.5 V, or adjustable defaults. DCDC3 supports 800 mA and 90% efficiency with an adjustable 0.6 V to VINDCDC3 range.
The device is supplied in a 32-pin VQFN RHB package with a 5.00 mm x 5.00 mm body and exposed thermal pad. Recommended ambient operation is -40 C to 85 C, while recommended junction operation is -40 C to 125 C.
