1 LTM8026. 36 VIN, 5A CVCC Step-Down Module Regulator FEATURES DESCRIPTION. n Complete Step-Down Switch Mode Power Supply The LTM 8026 is a 36 VIN, 5A constant-voltage, constant- 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 to 24V. CVCC operation n to 24V Output Voltage allows the LTM8026 to accurately regulate its output n Selectable Switching Frequency: 100kHz to 1 MHz 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.

2 Only resistors to set the output voltage and n ( 15mm ) LGA and ( frequency and the bulk input and output filter capacitors 15mm BGA Packages are needed to finish the design. The LTM8026 is packaged in a thermally-enhanced, APPLICATIONS compact ( 15mm) overmolded land grid ar- 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.
