This reference design allows a digitally programmable power supply to power an ultrasound transmit circuit for continuous wave (CW) mode from a 24-V bus. There are two outputs adjustable from ±2.5 to ±12 V under user software control. These outputs can provide up to 2 A with very low ripple and noise on both positive and negative regulator outputs. The power supply is scalable for higher output currents up to 3 A by adding more regulators in parallel. The power supplies can also be synchronized to an external clock.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
