Evaluates: MAX15048/MAX15049 19-5149 Rev 0 1/10 MAX15049 Evaluation Kit General Description Features The MAX15049 evaluation kit (EV kit) is a fully assembled S Triple-Output Power Supply and tested PCB that demonstrates the capabilities of VOUT1 (3.3V, 3A) the MAX15049. The MAX15049 is a high-performance, VOUT2 (1.8V, 3A) triple-output synchronous buck controller with sequenc- VOUT3 (1.2V, 6A) ing capability. The EV kit requires a 5V to 16V (12V, typ) DC input-voltage range for normal operation. S 5.5V to 16V Input-Voltage Operation (Design The MAX15049 EV kit outputs are configured for 3.3V, Optimized for 12V Input) 1.8V, and 1.2V. They provide a load current of 3A, 3A, S Optional 4.5V to 5.5V Input-Voltage Operation and 6A, respectively. The EV kits switching frequency S 500kHz Switching Frequency per Converter is set to 500kHz, but can be programmed up to 1.2MHz S Programmable Switching Frequency Up to 1.2MHz by replacing a resistor. The EV kit comes configured for sequencing (MAX15049) and is capable of prebias S Sequencing Operation (Tracking Possible with startup. The EV kit can also be used to evaluate the Component Changes) MAX15048 for tracking applications by changing a few S PGOOD Power Monitoring components. The PGOOD logic signal output pad is S Small 1.5in x 1in Circuit Footprint provided for circuit monitoring. S 92.8% Peak Efficiency for OUT1 The MAX15049 EV kit comes with a MAX15049ETJ+ installed. To evaluate the MAX15048, contact the factory S Fully Assembled and Tested for samples of the pin-compatible MAX15048ETJ+. Ordering Information PART TYPE MAX15049EVKIT+ EV Kit +Denotes lead(Pb)-free and RoHS compliant.
