MIC28514規(guī)格書詳情
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.
