LTM8025 regulator

Linear Technology Corp. rolls a 3A high voltage DC/DC ?Module regulator system that offers up to 36V input voltage and 24V output voltage. The 24V output voltage range suits 12V to 20V intermediate bus systems, while the 36V input provides input protection in 24V and 28V systems.

The LTM8025 is a complete DC/DC solution that includes a DC/DC controller IC, power switches, inductor, compensation circuitry and input and output bypass capacitors. The module is a molded plastic 9mm x 15mm x 4.32mm LGA surface mount package that weighs less than 1.8g. Because of high input and output voltage ratings, the LTM8025 is well suited for applications such as 24V industrial, 28V medical and avionics, as well as 12V communication systems.

The LTM8025 is a current mode, switching DC/DC point-of-load regulator system with 3.6V to 36V input operation that can regulate an output voltage from 0.8V to 24V, adjustable with one resistor. Two devices can be paralleled for current sharing if more than 3A output is required. Encapsulated packaging protects the circuit components against mechanical, chemical and ambient factors, thus improving the reliability of the design. The LTM8025 is rated for operation from -40C to 125C and -55C to 125C. It is RoHS compliant, and with gold-plated pads, both Pb and Pb-free solder can be used during board assembly. 1,000-piece pricing starts at $8.95.
