The MIC28514 is an adjustable frequency, synchronous buck regulator that features a unique adaptive on-time control architecture. The MIC28514 operates over an input supply range of 4.5V to 75V, and provides a regulated output of up to 5A of output current. The output voltage is adjustable down to 0.6V with an accuracy of ±1%. Hyper Speed Control architecture allows for an ultra-fast transient response, while reducing the output capacitance, and also makes high-VIN/low-VOUT operation possible.


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
