178002, EVAL BOARD, BUCK REGULATOR
MagI³C power supply reference design board demonstrates how a MagI3C power module can be used for applications that require additional power supply functionalities. An adjustable output current limit can be set from 0mA to the maximum continuous output current of the module, turning the module into a constant current source or still acting as a voltage source but with a user defined current limit. An electronic fuse can be implemented by triggering on the current limit LED and pulling the enable pin low to shut down the MagI3C power module immediately after a current limit event. Output voltage and current can have arbitrary waveforms. Typical applications include mini lab power supply, constant current source (can be individually adjusted), battery charger, super cap charger and high power LED driver.
• Current can be adjusted individually (0 - 2.5A)• Voltage can be adjusted individually (0 - 15V)• Current and voltage dynamically adjustable by external microcontroller (using PWM)• DC• DC converter used is MagI³C power module 171 021 501• Input voltage range from 7V to 36V• Maximum output power of 37.5W, switching frequency of 1MHz
