LTM8026 36V , 5A CVCC Step-Down IN Module Regulator FEATURES DESCRIPTION n Complete Step-Down Switch Mode Power Supply The LTM 8026 is a 36V , 5A constant-voltage, constant- IN n Constant-Voltage Constant-Current Operation current (CVCC) step-down Module regulator. Included in n Selectable Output Current Up to 5A the package are the switching controller, power switches, n Parallelable for Increased Output Current, Even inductor and support components. Operating over an from Different Voltage Sources input voltage range of 6V to 36V, the LTM8026 supports n Wide Input Voltage Range: 6V to 36V an output voltage range of 1.2V to 24V. CVCC operation n 1.2V to 24V Output Voltage allows the LTM8026 to accurately regulate its output n Selectable Switching Frequency: 100kHz to 1MHz current up to 5A over the entire output range. The output n SnPb or RoHS Compliant Finish current can be set by a control voltage, a single resistor or n Programmable Soft-Start a thermistor. Only resistors to set the output voltage and n (11.25mm 15mm 2.82mm) LGA and (11.25mm frequency and the bulk input and output filter capacitors 15mm 3.42mm BGA Packages are needed to finish the design. The LTM8026 is packaged in a thermally-enhanced, compact (11.25mm 15mm) overmolded land grid ar- APPLICATIONS ray (LGA) and ball grid array (BGA) packages suitable for n SuperCap Charging automated assembly by standard surface mount equip- n General Purpose Industrial ment. The LTM8026 is available in SnPb (BGA) or RoHS n Extreme Short-Circuit Protection or Accurate Output compliant terminal finish.
