Description
The LTM®8026 is a 36VIN, 5A constant-voltage, constant-
current (CVCC) step-down µModule® regulator. Included in
the package are the switching controller, power switches,
inductor and support components. Operating over an
input voltage range of 6V to 36V, the LTM8026 supports
an output voltage range of 1.2V to 24V. CVCC operation
allows the LTM8026 to accurately regulate its output
current up to 5A over the entire output range. The output
current can be set by a control voltage, a single resistor or
a thermistor. Only resistors to set the output voltage and
frequency and the bulk input and output filter capacitors
are needed to finish the design.
The LTM8026 is packaged in a thermally-enhanced,
compact (11.25mm × 15mm) overmolded land grid ar-
ray (LGA) and ball grid array (BGA) packages suitable for
automated assembly by standard surface mount equip-
ment. The LTM8026 is available in SnPb (BGA) or RoHS
compliant terminal finish.
