DESCRIPTION
The LTM®8056 is a 58VIN, 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 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
grid array (BGA) package suitable for automated assembly
by standard surface mount equipment. The LTM8056 is
available with SnPB or RoHS compliant terminal finish.
