The LTM8055 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 LTM8055 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 LTM8055 is housed in a compact overmolded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8055 is RoHS compliant.

Product Detail

Demonstration circuit 2017A features the LTM8055, a 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 DC2017A is 12V and the input voltage range is 5V to 36V. The maximum output current is 6A and the switching frequency is 600kHz.
