Analog Devices / Maxim Integrated MAX17577EVKIT & MAX17578EVKIT Evaluation Kits

Analog Devices MAX17577EVKIT and MAX17578EVKIT Evaluation Kits provide a demonstration platform for the MAX17577 and MAX17578 DC-DC Converters in -12V and -5V output voltage applications. The MAX17577 and MAX17578 are high-efficiency, high-voltage, inverting, Himalaya synchronous DC-DC converters with integrated MOSFETs and internal compensation. 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 generates a -12V output (VOUT1) at load currents up to 0.8A from a 16V to 48V input supply and operates at 600kHz switching frequency. This Evaluation Kit features the MAX17577, which operates in Continuous Conduction Mode (CCM) at all loads, thus providing a constant frequency operation.

The MAX17578EVKIT 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 the MAX17578, which operates in Discontinuous Conduction Mode (DCM) for superior efficiency at light loads.

Analog Devices MAX17577EVKIT and MAX17578EVKIT Evaluation Kits are configured for optimum efficiency and component size. The Evaluation Kits feature programmable enable and input undervoltage-lockout (UVLO), soft-start, open-drain active-low RESET signal, and external clock synchronization. These Evaluation Kits also provide a good layout example, which are optimized for conduction, radiated EMI, and thermal performance.
