TPS6594-Q1 Power Management IC (PMIC)

Texas Instruments TPS6594-Q1 Power Management IC (PMIC) provides four flexible multi-phase configurable step-down converters with 3.5A per phase and one additional step-down converter with 2A capability. All of the bucks can be synchronized to an internal 2.2MHz or 4.4MHz or an external 1MHz, 2MHz, or 4MHz clock signal. An integrated spread-spectrum modulation can be added to the synchronized buck switching clock signal to improve the device’s EMC performance, which can also be made available to external devices through a GPIO output pin. The device provides four LDOs: three with 500mA capability, which can be configured as load switches; one with 300mA capability and low-noise performance.
