Product Details

The MAX17645BEVKITB# and MAX17645DEVKITB# evaluation kits (EV kits) provide proven 5V designs to evaluate the performance of MAX17645B and MAX17645D high-efficiency, high-voltage, synchronous step-down DC-DC converters. The MAX17645BEVKITB# EV kit operates in constant frequency PWM (pulse-width modulation) mode at all loads and the MAX17645DEVKITB# EV kit operates in PFM (pulse-frequency modulation) mode at light loads to improve efficiency.

The EV kits are configured to demonstrate the optimum performance and component sizes for MAX17645B/ MAX17645D converter. The EV kits support a wide operating input range of 7V to 36V and are configured for 5V output. The EV kits deliver up to 1A at a switching frequency of 650kHz.

The features of the EV kits include adjustable input undervoltage lockout, fixed internal soft-start, and open-drain active-low RESET signal for output voltage status monitoring. The EV kits also provide a good layout example, which is optimized for conducted, radiated EMI, and thermal performance.
