MIC38300 SHORT OVERVIEW
The MIC38300 device is a high-efficiency, step-down converter, part of the HELDO
(High Efficiency Low Dropout) family. It is available with 2.2A output current in
continuous operation, 3A peak operation for the MIC38300 device or with an output
current of 1.5A for the MIC38150.
The MIC38300 fully integrates a switcher, the coil, switching MOSFETs and 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 70 dB at 1 kHz and
low output ripple, less than 5 mV

. All of these, combined with the optimized archi-
tecture of the MIC38300 device that is targeting fast transient response, make this part
ideal for powering ASICs, FPGAs or point of load applications.
