Product Overview
The TPS62913 is a Texas Instruments low-noise synchronous buck converter for Power_Management designs requiring regulated low-voltage rails from a 3.0 to 17 V input. Its recommended output range is 0.8 to 5.5 V, with TPS62913 output current specified from 0 to 3 A. The converter supports fixed 2.2 MHz or 1 MHz switching operation and can synchronize to an external clock applied at EN/SYNC.
Noise and supply rejection parameters are central to the device profile. Extracted datasheet limits include output 1/f noise below 20 uVrms from 100 Hz to 100 kHz, output voltage ripple below 10 uVrms after a ferrite bead filter, and power supply rejection ratio greater than 65 dB up to 100 kHz. Electrical data also lists 65 dB and 70 dB typical PSRR under stated VIN, VOUT, current, frequency, and output-network conditions.
The device is supplied in a 10-pin QFN RPU package, 2.0 mm x 2.0 mm, 0.5-mm pitch. Recommended external network values include 5 uF minimum effective input capacitance, 2.2 uH or 4.7 uH nominal effective output inductance, 40 uF minimum effective output capacitance, and optional filter inductance and capacitance ranges from the datasheet facts.
