3.1 Electrical Performance Specifications

The inductor used in this EVM is a 4.7-µH inductor which is rated for 25A. There are chances of heating up this inductor if operated at higher switching frequency and higher current level. Please monitor the temperature of the inductor and add external fan cooling if necessary. The switching frequency is set by an external PWM signal (between 0 V and 5 V). The duty cycle of this PWM signal sets the duty cycle of the half-bridge module.
