Maxim Integrated launches High-Voltage Regulator – MAX17503

System designers can now achieve more efficiency across a wide industrial voltage range with the MAX17503 synchronously-rectified DC-DC step-down converter from Maxim Integrated Products. By integrating two MOSFET switches and eliminating an external Schottky diode, the MAX17503 delivers higher-power efficiency, operating 50% cooler than any other industrial high-voltage DC-DC converter. It operates from 4.5V to 60V and delivers up to 2.5A output current. The MAX17503 saves up to 50% space and reduces component count by 75%.

The MAX17503 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, the MAX17503 is ideal for programmable logic controllers (PLCs), process variable transmitters (PVTs), computerized numerical control (CNC), and distributed I/O modules in industrial process control, motor control, power grid, and building automation applications.

Synchronous rectification in switching regulators at high voltages and currents on a single chip requires advanced process technology and innovative IC design. As the first company to bring synchronous rectification to high-voltage applications, Maxim delivers unparalleled power efficiency and size advantage to industrial customers who can now leap frog their competition, said Anil Telikepalli, Director of Business Management, Maxim Integrated.

The MAX17503 is available in a 20-pin, 4mm x 4mm TQFN package at a starting price of $1.94.
