Output 2 and Output 3 each deliver up to 2A over an adjustable 0.8V to 5.5V range, while Output 1 is a controller output for an external FET — useful for a higher-current rail the on-chip bucks cannot source alone. ## 4.9 MHz switching — shrinking the magnetics The 4.9 MHz switching frequency lets the designer use small-value inductors and ceramic output capacitors, keeping the total power-stage footprint tight. That frequency also pushes the fundamental switching noise above the AM band, simplifying filtering in radio and telematics applications. ## Integrated sequencer and LED driver — fewer external parts An on-chip power sequencer handles the turn-on and turn-off order for the five outputs, eliminating the external supervisor or CPLD normally needed to sequence an SoC or FPGA. The integrated LED driver can serve cluster backlighting or indicator circuits, further consolidating the BOM.","metaTitle":"TPS65310AQRVJRQ1 Automotive PMIC, 5 Outputs, 4.9 MHz","metaDescription":"Texas Instruments TPS65310AQRVJRQ1 automotive PMIC: 5 outputs (3 buck, 1 boost, 1 LDO), 4.8V–40V input, 4.9 MHz switching, -40°C to 125°C.
