Small regulator for applications requiring strict reliability and high durability

Analog Devices offers the Power by Linear LTM8002, a step-down DC-DC µModule (power module) regulator with a 40V input voltage rating (42V abs max) and 2.5A of continuous (3.5A peak) output current, housed in a 6.25mm x 6.25mm x 2.22mm BGA package. The device includes a switching regulator controller, power switches, inductor and other supporting components. Only the bulk input, output capacitors and two resistors are required to complete the design. The device’s pinout is FMEA-compliant, so in the event of short-circuiting to GND, short-circuit to a neighbouring pin, or if the pin is left floating, the output voltage safely remains at or below the regulated voltage. The maximum junction temperature of the H grade is 150C and I grade is 125C. The device H grade can deliver 2.8A of output current up to 105C ambient without a heat sink or airflow under the12VIN to 5VOUT condition. The device’s wide input voltage range, FMEA compliant pinout, high-temperature operation and small solution give an ideal point-of-load regulator for applications demanding stricter reliability and greater durability, such as industrial and automotive equipment.
