TPS650250 Power Management ICs Texas Instruments TPS650250 Power Management ICs contain 6 channels, which consist of 3 buck converters and 3 LDO, in a small 5x5mm QFN package. This TI device lets designers adjust output voltages by using external resistor dividers. The TPS650250 also features Dynamic Voltage Scaling (DVS) at the core voltage, DCDC3. The voltage can be changed during operation by changing the value of the external resistor. All rails can be sequenced using the EN pins.
