150°C, FMEA-compliant pinout, 40V, 2.5A µModule regulator in 6.25mm x 6.25mm BGA package

21 August 2018

Analog Devices announces 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 LTM8002 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 LTM8002’s pinout is FMEA (failure mode effects analysis) compliant, so in the event of short-circuit to GND, short-circuit to a neighboring pin or if the pin is left floating, the output voltage safely stays at or below the regulated voltage. The maximum junction temperature of the H grade is 150°C and I grade is 125°C.

The LTM8002 

H grade can deliver 2.8A of output current up to 105°C 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 provide an ideal point-of-load regulator for applications that require stricter reliability and higher durability, such as automotive and industrial equipment.

The switching frequency is adjustable with a resistor or can be synchronised to an external clock from 200kHz to 3MHz, to avoid interference by operating the device in or out of a system’s specific frequency or frequency range. The LTM8002 has four modes: Burst Mode® operation, pulse-skipping mode, pulse-skipping mode with spread spectrum mode, and external synchronisation mode.

The quiescent current in Burst Mode operation is 25µA, ideal for battery-operated systems, specifically for systems that require a ‘keep alive’ function.

The output voltage is adjustable with one resistor from, 0.97V to 18V – or fixed at 3.3V. This wide output voltage range provides the versatility of using one product to generate common system bus voltages of 3.3V, 5V, 12V, and 15V.

The LTM8002 is operational from -40°C to 125°C or -40°C to 150°C. For more information, visit www.analog.com/LTM8002.
