DC-DC step down converter delivers high power efficiency

The MAX 17503 enables system designers can now achieve more efficiency across a wide industrial voltage range. It operates from 4.5V to 60V and delivers up to 2.5A output current. The new device saves up to 50% space and reduces component count by 75 %. Industrial equipment has been shrinking with no heatsinks or fans. System designers also struggle to secure enough design margins against input voltage transients to meet fail-safe standards. The DC-DC converter provides the widest input operating voltage range, significantly reduces heat dissipation, and improves reliability.

 Designers with widely varying loads can use pulse-frequency modulation (PFM) for enhanced efficiency at light load currents. Specifically designed for industrial control and automation applications, device targets programmable logic controllers (PLCs), process variable transmitters (PVTs), computerised numerical control (CNC), and distributed I/O modules in industrial process control, motor control, power grid, and building automation applications.
