EVAL-LTM4703-AZ

EVAL-LTM4703-AZ is an evaluation board for 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. The EVAL-LTM4703-AZ evaluation board's default switching frequency is 400kHz. An external resistor is placed from the RT pin to GND (R7) to set the switching frequency.
