The LTM8050 is a 58VIN, 2A step down μModule® (power module) converter. Included in the package are the switching controller, power switches, inductor and all support components. Operating over an input voltage range of 3.6V to 58V, the LTM8050 supports an output voltage range of 0.8V to 24V and a switching frequency range of 100kHz to 2.4MHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design.
The LTM8050 is packaged in a 9mm × 15mm × 4.92mm ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8050 is available with SnPb (BGA) or RoHS compliant terminal finish.

Evaluation Kits (1)
Demo circuit DC1723A features the LTM8050, a μModule® (micromodule) step-down converter that can deliver up to 2A of output current. DC1723A is designed for a 5V, 2A output from a 7.5V to 58V input at 400kHz. The wide input range of the LTM8050 allows a variety of input sources such as automotive batteries and industrial supplies. At light loads, the LTM8050 enters Burst Mode® operation to maintain high efficiency and low output ripple over a broad current range. The user adjustable features of the LTM8050 such as output voltage, switching frequency, soft-start, and power good can be changed on DC1723A simply by modifying or installing the appropriate resistors and/or capacitors.
