DESCRIPTION
The LTM®8055/LTM8055-1 is a 36VIN, buck-boost µModule® (micromodule) regulator. Included in the package are the switching controller, power switches, inductor and support ponents. 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 plete the design. Other Features such as input and output average current regulation may be implemented with just a few ponents. The LTM8055/LTM8055-1 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/LTM8055-1 is housed in a pact overmolded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8055/LTM8055-1 is RoHS pliant.
