Evaluates: MAX5066 19-4004 Rev 1 8/06 MAX5066 Evaluation Kit General Description Features The MAX5066 evaluation kit (EV kit) is a two-phase, 5V to 16V Input Voltage Range (Design Optimized dual-output buck converter with a 5V to 16V input volt- for 12V Input) age range. The MAX5066 EV kit provides dual 0.8V and Output Voltages 1.3V output voltages. It delivers up to 10A output cur- 0.8V at 10A (Adjustable from 0.61V to 5.5V) rent for each output with 90% efficiency. The MAX5066 1.3V at 10A (Adjustable from 0.61V to 5.5V) EV kit uses average current-mode control and operates at 500kHz switching frequency per phase where each 500kHz Switching Frequency phase is 180 out-of-phase with respect to the other. Both Outputs Can be Paralleled for Higher This EV kit is a fully assembled and tested circuit Current Capability (Using Mode Function) board. Both outputs are adjustable between 0.61V and 5.5V by changing feedback resistors R4, R5, R6, and Average Current-Mode Control Provides Accurate R7. Additional features include thermal-shutdown and Current Limit hiccup-mode short-circuit protection.
