MIC2165
Adaptive On-Time DC-DC Controller
Featuring HyperLight LoadВ®
Hyper Speed Controlв„ў Family General Description Features The Micrel MIC2165 is a synchronous adaptive on-time
buck controller targeting high-performance, cost-sensitive
applications such as set-top boxes, gateways, routers,
computing
peripherals,
and
telecom/networking
equipment.
The MIC2165 operates over a supply range of 4.5V to
28V. It has an internal linear regulator which provides a
regulated 5V supply to power the internal control circuitry.
MIC2165 operates at a constant 600kHz switching
frequency and can be used to drive up to 25A of output
current. The output voltage is adjustable from 0.8V to
5.5V.
A unique Hyper Speed Controlв„ў architecture enables
ultra-fast transient response while reducing the output
capacitance and also makes High VIN/Low VOUT operation
possible.
A UVLO feature is provided to ensure proper operation …
