ADM00822

ADM00822 is a MIC38300A evaluation board. It supports evaluation of the MIC38300 device. Applications include Power Management - Voltage Regulator, Low Dropout Linear Regulator. The MIC38300A device is a high-efficiency, step-down converter, part of the high efficiency low dropout family. It is available with 3A output current in continuous operation, 4A peak operation. The MIC38300A fully integrates a switcher, a coil, switching MOSFETs and an LDO, resulting in a highly efficient solution for stepping down a wide range of input voltages, while providing a good PSRR (Power Supply Rejection Ratio) of 70dB at 1kHz, as well as low output ripple, less than 5mV peak-to-peak. All of these, combined with the optimized architecture of the MIC38300A device that is targeting a fast transient response, make this part ideal for powering ASICs, FPGAs or point of load applications.
