EVAL-LTM4702-AZ

Evaluation board EVAL-LTM4702-AZ is a step-down DC/DC switching converter featuring the LTM®4702 μModule® regulator. The evaluation board is designed to deliver 8A maximum output current from a 4V to 16V input. The LTM4702 employs Silent Switcher® architecture with internal hot loop bypass capacitors to achieve both low EMI and high efficiency. The LTM4702 contains a current mode regulator IC, power inductor, and a modest amount of input and output capacitance. A single resistor (R3) sets the output voltage, providing unity gain operation over the output range, resulting in virtually constant output noise independent of output voltage. The EVAL-LTM4702-AZ evaluation board default switching frequency is 800KHz. An external resistor is placed from RT pin to GND (R7) to set the switching frequency. SYNC pin programs three different operating modes (JP1 jumper): select PULSE for pulse-skipping mode All registered trademarks and trademarks are the property of their respective owners.

• Typical efficiency is 80.5%
