Output 11 V / 12 A

Description

The EVAL-LTM4703-AZ evaluation board is a step-down dc-to-dc switching converter featuring the LTM®4703 μModule® (micromodule) regulator. The EVAL-LTM4703-AZ is designed to deliver 12A maximum output current from a 4V to 16V input. The LTM4703 employs Silent Switcher® architecture with internal hot loop bypass capacitors to achieve both low electromagnetic interference (EMI) and high efficiency. The LTM4703 contains a current mode regulator IC, a 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.
