This reference design is built to power the next generation 128-channel ultrasound smart probe that adopts our new generation transmitter and receiver. The compact size (88mm × 45mm × 20mm) includes all power functions for a 128-channel smart probe with >80% efficiency. This transformerless high-voltage power supply (±75V at 25mA), new boost regulator enables the reference design to meet most smart probe applications.
