Overview

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.

Features
  • Transformerless, dual-rail, high-voltage (±75V at 25mA) generation from 5V USB Type-C® in single stage implementation to meet component height requirement of <5mm
  • Compact board size (less than 88mm × 45mm × 20mm)
  • End-to-end system efficiency of 80% running at full load
  • Enable and disable supplies for power optimization and all rails can be synchronized to external clock
  • Accurate real-time power consumption measurement using high-performance current sensing amplifier INA231
  • High-speed data acquisition over USB 2.0 up to 480Mbps
