40V, 3.5A µModule Regulator is FMEA Compliant,Operates up to 150°C Junction Temperature
2016-06-30 | ReturnThe LTM8003 operates from an input voltage range of 3.4V to 40V and has an adjustable output voltage range of 0.97V to 18V. The switching frequency is adjustable via an external resistor or can be synchronized to an external clock from 200kHz to 3MHz. The LTM8003 has four operation modes: Burst Mode® operation, pulse skip mode, pulse skip mode with spread spectrum and external synch mode. The quiescent current in Burst Mode operation is 25µA (max), so the LTM8003 is well suited for battery operated systems, specifically “keep alive” systems.
The efficiency at 12VIN to 3.3VOUT is 90% and the LTM8003 delivers 3.5A of output current up to 100°C ambient without a heat sink or airflow. The LTM8003 includes a switching regulator, inductor and other supporting components in a 6.25mm x 9mm x 3.32mm BGA package. Only the bulk input and output capacitors and a few resistors are required to complete the design.
The LTM8003 is operational from -40°C to 125°C or -40°C to 150°C. 1,000-piece pricing starts at $11.30 each. For more information, visit www.linear.com/product/LTM8003.
