The LTM8026 is a 36VIN, 5A constant-voltage, constant-current (CVCC) step-down μModule® (power module) 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 array (LGA) and ball grid array (BGA) packages suitable for automated assembly by standard surface mount equipment. The LTM8026 is available in SnPb (BGA) or RoHS compliant terminal finish.
