The LTM8054 is a 36VIN, buck-boost µModule® (micromodule) regulator. Included in the package are the switching controller, power switches, inductor and support components. A resistor to set the switching frequency, a resistor divider to set the output voltage, and input and output capacitors are all that are needed to complete the design. Other features such as input and output average current regulation may be implemented with just a few components. The LTM8054 operates over an input voltage range of 5V to 36V, and can regulate output voltages between 1.2V and 36V. The SYNC input and CLKOUT output allow easy synchronization.
The LTM8054 is housed in a compact overmolded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8054 is RoHS compliant.

Evaluation Kits (1)
Demonstration circuit 2016A features the LTM8054, a synchronous buck-boost μModule regulator that accepts input voltages lower, higher or the same as the output, but is also highly efficient due to its four-switch architecture. The output for DC2016A is 12V and the input voltage range is 6V to 35V – see the LTM8054 data sheet for application circuits with input voltages up to 36V. The maximum output current of DC2016A is 3A and the switching frequency is 600kHz.
