The integrated sequencer controls power-up and power-down order — no external supervisor or CPLD needed for multi-rail SoC start-up. Input voltage range is 2.5V to 5.5V, covering standard 3.3V and 5V rails. The three buck converters share a fixed 2.3 MHz switching frequency, which keeps the inductor small enough for space-constrained designs. ## Output current and voltage flexibility Output 1 delivers up to 3.5 A with an adjustable range of 0.6V to 3.4V. Outputs 2 and 3 each deliver up to 2 A over the same voltage window. The four LDOs handle lower-current rails for analog or I/O supplies. ## Package and mounting — thermal pad matters Surface-mount only. No single-source risk flagged — TI maintains multiple fabs for this node.","metaTitle":"TPS6521905RHBR PMIC – 7-Channel Power Management IC with","metaDescription":"Texas Instruments TPS6521905RHBR: 2.5V–5.5V input, 7 outputs (3 buck + 4 LDO), 2.3 MHz switching, -40°C to 105°C, active lifecycle.
