The LTM8020 from Linear Technology is the first in a new family of DC/DC µModule™ regulator systems that operate from higher voltage input supplies of up to 36 V (40 V max). The LTM8020 is a 200mA complete DC/DC solution that includes a DC/DC controller IC, power switches, inductor, compensation circuitry and input and output bypass capacitors. This solution is extremely compact at only 6.25 x 6.25mm and low profile at 2.3mm in height and needs – due to its very high efficiency factor – no heatsink.

Target applications are systems with 24 V and 28 V input supply rails such as medical, industrial, avionics and automotive.

The LTM8020 is a complete 200mA, current mode, switching DC/DC point-of-load regulator system in a LGA (Land Grid Array) surface-mount package. The package can be mounted on the back side of a circuit board, allowing more room for digital ICs on the top side. Input voltage range is from 4 V to 36 V and output can be adjusted with only one resistor from 1.25 V to 5 V. Encapsulated packaging protects the circuit components against mechanical, chemical and ambient factors, thus improving the reliability of the design.

The LTM8020 is rated for operation from –40 ºC to 85 ºC and is RoHS-compliant. Its gold-plated pads allow both Pb- and Pb-free solder to be used during board assembly. 1,000-piece pricing starts at $4.95 each.
