General Description

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. This adaptive on-time control architecture

combines the advantages of fixed frequency operation

and fast transient response in a single device.

The MIC28514 offers a full suite of features that ensure

the protection of the Integrated Circuit (IC) during Fault

conditions. These features include Undervoltage

Lockout (UVLO) to ensure proper operation under

power sag conditions, soft start to reduce inrush current,

Hiccup mode short-circuit protection and thermal shutdown.
