The MAX17577EVKIT# and MAX17578EVKIT# evaluation kits (EV kits) provide a proven design to evaluate the MAX17577 and MAX17578 high-efficiency, high-voltage, inverting, Himalaya synchronous DC-DC converters. The devices generate output voltages (VOUT) from -0.9V to -36V and can deliver up to 1A of load current from a wide 4.5V to 60V-|VOUT| input voltage range.
The MAX17577EVKIT# EV kit generates -12V output (VOUT1) at load currents up to 0.8A from a 16V to 48V input supply and operates at 600kHz switching frequency. This EV kit configuration features MAX17577 that operates in continuous conduction mode (CCM) at all loads, thus, providing a constant frequency operation.
The MAX17578EVKIT# EV kit generates -5V output (VOUT2) at load currents up to 1A from a 16V to 55V input supply and operates at 600kHz switching frequency. This EV kit configuration features MAX17578 that operates in discontinuous conduction mode (DCM) for superior efficiency at light loads.
The EV kits are configured for optimum efficiency and component size. The EV kits feature programmable enable and input undervoltage-lockout (UVLO), softstart, open-drain active-low RESET signal and external clock synchronization. The EV kits also provide a good layout example, which are optimized for conducted, radiated EMI, and thermal performance.
