The TPS650250RHB from Texas Instruments is an integrated Power Management IC (PMIC) designed for Li-Ion or Li-Polymer battery-powered systems requiring multiple power rails. It features three high-efficiency step-down (buck) converters (1.6A, 0.8A, 0.8A), a 30mA LDO for always-on rail, and two 200mA general-purpose LDOs. The device operates from a single Li-Ion cell (2.5-6V input) and provides configurable output voltages through external resistor dividers. The 2.25MHz switching frequency allows use of small external inductors.<\/p>\n

It combines three high-efficiency step-down converters with three LDO regulators in a single 32-pin VQFN package, providing all necessary power rails for a processor-based system. The DCDC1 converter delivers up to 1.6A for system I\/O voltage, while DCDC2 and DCDC3 provide 0.8A each for memory and processor core voltages respectively. All three converters feature automatic power-save mode at light loads for maximum efficiency across the entire load range. The device supports dynamic voltage scaling on DCDC3 for processor power optimization.","working_principle":"The TPS650250 operates from a single Li-Ion cell input (2.5-6V) and generates multiple regulated output rails. Each step-down converter uses a synchronous rectification buck topology with integrated power MOSFETs, operating at a fixed 2.25MHz switching frequency. In PFM mode (MODE pin low), the converters enter power-save mode at light loads, skipping pulses to maintain efficiency. In forced PWM mode (MODE pin high), all converters operate at fixed frequency for lowest output voltage ripple. The DCDC3 output supports dynamic voltage management through an external resistor divider, allowing real-time core voltage adjustment. The two 200mA LDOs use PMOS pass transistors for low dropout and can be powered from any DCDC output. The 30mA Vdd_alive LDO remains active in all power states. The PWRFAIL comparator monitors the battery voltage and provides an early warning output.","pin_description":"
