Product Overview
TPS62912 is a Texas Instruments synchronous buck converter for Power_Management rails requiring regulated low-voltage output from a higher input supply. Recommended operating conditions specify a 3.0 V to 17 V input range, 0.8 V to 5.5 V output range, and 0 A to 2 A output current for TPS62912.
The device uses fixed-frequency peak current mode control with 2.2 MHz or 1 MHz switching options. Electrical characteristics include 57 mOhm typical high-side FET on resistance and 20 mOhm typical low-side FET on resistance at VIN >= 5 V, with feedback regulation centered at 0.8 V.
Noise and supply rejection specifications support low-noise power rails: output 1/f noise is listed below 20 uVrms from 100 Hz to 100 kHz, output ripple is below 10 uVrms after a ferrite bead, and PSRR is greater than 65 dB up to 100 kHz. The 10-pin QFN RPU package is 2.0 mm x 2.0 mm with 0.5-mm pitch, and the operating junction temperature range is -40 to 150 degC.
