TIDA-01371 Programmable ±100-V, High-Current, Floating Linear Regulator Reference Design for Ultrasound Systems | TI.com

TIDA-01371: Ultrasound transmitters require a stable programmable DC power source to drive high current into piezo transducers during the transmission. The TIDA-01371 reference design demonstrates a positive and negative linear regulator that can provide output voltages varying from ±2.5 to ±100V. The programmability (meant to come from a DAC) is implemented using external control voltages. The low-noise performance helps in replacing passive and active noise filters with off-the-shelf low-noise positive and negative LDO regulators and a circuit to float the ground of the regulators. In addition, it uses external power MOSFETs to scale the current capability of regulators to support special imaging modes such as shear wave, or elastography, mode. In order to provide extremely high currents to the transducers, large input capacitors can provide high energy for 1ms of duration keeping the average current drawn from this power supply very low.
