TIDA-01352, 400W Continuous, Scalable, ±2.5 to ±150 V, Programmable Ultrasound Power Supply Reference Design

Per contattare il Servizio Clienti.

• TIDA-01352, Reference design enables modular and efficient power scaling capability by providing a solution for digitally programmable power supply for powering ultrasound transmit circuit. The design uses push-pull topology to generate high-voltage (HV) and low (LV) or MID- voltage power supplies. The HV rails are programmable from ±50V to ±150V, whereas the LV or MID rails are programmable from ±2.5V to ±50V. The power supply is capable of providing a continous power of 100-W on each rail. The programmability is implemented using onboard, 12-bit digital-to-analog converters (DACs). All the power supply rails are capable of being synchronized to a master clock. The design is scalable and modular allowing same supply to be duplicated or removed depending on number of channels and number of levels of pulser
