Texas Instruments

The TPS4030x is a family of cost-optimized synchronous buck controllers that operate from 3-V to 20-V input. The controller implements a voltage-mode control architecture with input-voltage feed-forward compensation that responds instantly to input voltage change. The switching frequency is fixed at 300 KHz, 600 KHz or 1.2 MHz. Read more...

Provides additional stable voltage in the middle of ADC input range to bias input bipolar signals for VRED and a second highly-accurate voltage (VBIAS) that can be used to bias the input bipolar signals. The REF20xx offers excellent temperature drift (8 ppm/°C, max) and initial accuracy (0.05%) on both the VREF and VBIAS outputs while operating at a quiescent current less than 430... Read more...
