MAX17673AEVKIT#

MAX17673AEVKIT# is an evaluation kit (EV kit) which provides a proven design to evaluate the MAX17673A 60V, 1.5A high efficiency, synchronous buck converter with integrated, dual 5.5V, 1A buck converters. The EV kit is preset for 5V output at a load current of up to 1.5A from the high voltage (HV) buck converter, and 3.3V and 1.8V outputs at load currents up to 1A each from the low-voltage (LV) buck converters. The HV buck converter is programmed to operate at 400kHz, and the LV buck converters are programmed to operate at 2MHz, for optimum efficiency and component sizes. The output of the HV buck converter is connected to the input of the LV buck converters. The EV kit features adjustable input undervoltage lockout and soft-start for the HV buck converter and powerOK (POK_) signals for all three buck converters.

• Three synchronous DC-DC buck converter outputs from a single HV input
• Wide 7V to 60V input range for HV buck converter
• Optional external supply I/P connections for LV buck converter(4.5 to 5.5V(LVA), 2.7 to 5.5V(LVB))
• Enable/UVLO input, resistor-programmable UVLO threshold for HV buck converter
• Programmed 1ms soft-start time for HV buck converter
• Internal 4096 clock cycles soft-start time for LV buck converters
• Selectable PWM and PFM modes of operation, external clock synchronization
• Independent Power-OK (POK-) O/P for 3 buck converters, overcurrent and overtemperature protection
• Low-profile, surface-mount components, proven PCB layout, fully assembled and tested
• Complies with CISPR 22 (EN 55022) Class B conducted and radiated emissions limits
