DESCRIPTION

µModule Regulator

(micromodule) regulator. Included in the package are the

switchingcontroller,powerswitches,inductorandsupport

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 LTM8056 operates over an input volt-

age range of 5V to 58V, and can regulate output voltages

between 1.2V and 48V. The SYNC input and CLKOUT

output allow easy synchronization.

The LTM8056 is housed in a compact overmolded ball

gridarray(BGA)packagesuitableforautomatedassembly

by standard surface mount equipment. The LTM8056 is

available with SnPB or RoHS compliant terminal finish.
