MANSFIELD, TEXAS — Mouser Electronics, Inc. delivers the Maxim MAX17503 Step-Down DC-DC converter, with a 60 volt maximum input voltage, and up to 2.5 amps of output current.
The Maxim MAX17503 available from Mouser Electronics is extremely flexible, operating over an input voltage range of 4.5V to 60V and delivering output voltages from 0.92V to a maximum of 90% of the input voltage. These wide ranges allow designers to reduce the number of DC-DC regulators in stock. Peak efficiency is greater than 90%. A detailed datasheet provides directions for choosing the proper external components for an application circuit's requirements. Operational temperature is from -40°C to +125°C, with thermal shutdown kicking in at 165°C.
A robust internal protection mechanism protects the device from high input voltages and short-circuit conditions. Hiccup-mode protection drops the output voltage to zero for a short time and then resumes normal voltage output, useful for circuit protection from current spikes that can occur when fans or motors are suddenly powered on.
