STMicroelectronics STEVAL-ISA084V1BOARD & REF DESIGN
The STMicroelectronics STEVAL-ISA084V1 is a demonstration board that uses the ST1S40, a 4 A peak, 800 kHz fixed-frequency PWM synchronous step-down converter. It is designed to provide a complete solution for audio amplification and USB charging applications. The board includes a USB Type-C connector, a 3.5 mm audio jack, and a DC power jack. It also features a high-efficiency synchronous buck converter, a low-noise audio amplifier, and a USB charger. The board is designed to be used with a wide range of input voltages, from 4.5 V to 28 V, and can provide up to 4 A of output current. The board also includes a variety of protection features, such as over-current, over-voltage, and short-circuit protection.
