Silent Switcher, 42 VIN, 2.5 A µModule Regulator in 6.25 mm × 6.25 mm BGA Package

Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTM8065, a µModule^® (power module) step-down regulator with up to 40 V input voltage (42 V abs max), which can safely operate from unregulated or fluctuating 12 V to 36 V input supplies in noisy environments such as industrial robotics, test and measurement, medical, factory automation and avionics systems.

The Silent Switcher^® architecture minimizes EMC/EMI emissions enabling the LTM8065 to pass CISPR 22 class B for use in noise-sensitive signal processing applications, including imaging and RF systems. The LTM8065’s small 6.25 mm × 6.25 mm × 2.32 mm BGA package includes a switching regulator controller, power switches, inductor and other supporting components. With only two 0805 sized capacitors and two 0603 sized resistors, the LTM8065’s solution occupies approximately 100 mm², about half the size of equivalent power level module solutions.

The LTM8065 can deliver 2.5 A of continuous (3.5 A peak) output current to a 5 V load from a 12 V input at up to 85 °C ambient without a heat sink or airflow. The output voltage is adjustable with one resistor from 0.97 V to 18 V. This wide output voltage range provides versatility, using one product to generate common system bus voltage of 3.3 V, 5 V, 12 V and 15 V. The switching frequency is adjustable by an external single resistor or can be synchronized to an external clock from 200 kHz to 3 MHz. It enables customer operation of the device in or out of the specific frequency. The LTM8065 has four modes: Burst Mode^® operation, pulse-skipping mode, pulse-skip mode with spread spectrum modulation and external synchronization mode. The quiescent current at burst mode is 8 µA, making it ideal for battery operating systems.

The LTM8065 operating temperature range is –40 °C to 125 °C. 1,000-piece pricing starts at $7.75 each. For more information, visit www.linear.com/product/ltm8065.
