The MIC28515/14 is a wide input range (4.5V-75V) integrated FET, 5A switching regulators. The MIC28515/14 is lever aging the latest enhanced high voltage COT controllers co-packaged with a pair of low FOM power trench N-Channel FETS with improved avalanche rating. The output voltage is adjustable down to 0.6V with +/- 1% accuracy. The MIC28515 offers a 'Mode" select pin allowing the user to choose in between Hyper Light load and Hyper Speed control operations.

Input voltage range: 4.5V to 75V
Adjustable output from 0.6V to 32V (Limited by duty cycle)
High Current capability of 5A
High Voltage Internal LDO for single supply operation8
Operation with both internal and external VDD
Output current up to 5A
Supports start up to pre-bias output
Internal compensator for tight output regulation
Enable function for low stand-by current
Programmable current limit and hiccup short circuit protection
Thermal shut down with hysteresis
