42VIN, 3.5A µModule Regulator for Industrial Systems, Factory Automation & Avionics in 6.25mm x 9mm BGA Package
The LTM8053 houses a switching regulator controller, power switches, inductor and other supporting components in a 6.25mm x 9mm x 3.32mm BGA package. With only two capacitors and two resistors the LTM8053’s solution occupies approximately 150mm², versus alternative solutions requiring up to 250mm² and twice as many components.
The LTM8053 delivers 3.5A of continuous (6A peak) output current, and its SHARE pin enables current sharing, allowing it to operate in parallel to deliver more current. The output voltage is adjustable with one resistor from 0.97V to 15V. This wide output voltage range provides versatility, so this one device generates common system bus voltages of 3.3V, 5V, 12V and 15V. The efficiency at 12VIN to 5VOUT is 90%. The LTM8053 delivers 3.5A of output current up to 85°C ambient without a heat sink or airflow (12VIN to 5VOUT).
The LTM8053 operating temperature range is -40°C to 125°C. 1,000-piece pricing starts at $9.66 each. For more information, visit www.linear.com/product/LTM8053.
