CN0508 Benchtop Power Supply

ADI's CN0508 circuit is a single-channel, 75 W benchtop power supply featuring an adjustable, wide output voltage range of 0 V to 27.5 V and current limiting/constant current operation (up to 3 A). With a Raspberry Pi®-compatible expansion header, electronic control through either a local touchscreen or over a wireless or wired network connection is possible. Output voltage can be controlled manually or by software, and a manual current-limit control sets the transition from constant-voltage to constant-current operation. The benchtop power supply features a hybrid buck/linear architecture, providing low output ripple and low output capacitance, excellent transient response, regulation to 0 V and 0 A, and low power dissipation that eliminates the need for heatsinks. The complete solution is low-cost, compact, and easily configured for standalone operation or integration into other equipment.
