MIC2164/-2/-3/C
Synchronous Buck Controllers
Featuring Adaptive On-Time Control
28V Input, Constant Frequency
Hyper Speed Control? Family
General Description
Features
The Micrel MIC2164/-2/-3/C are constant-frequency,
synchronous buck controllers featuring adaptive on-time
control. The MIC2164/-2/-3/C are the first products in the new
Hyper Speed Control? family of buck controllers introduced
by Micrel.
The MIC2164/-2/-3/C controllers operate over an input supply
range of 3V to 28V, and are independent of the IC supply
voltage. The devices are capable of supplying 25A output
current. While the MIC2164 operates at 300kHz, the
MIC2164-2 operates at 600kHz, and the MIC2164-3 operates
at 1MHz.
A unique Hyper Speed Control? architecture allows for ultra-
fast transient response while reducing the output capacitance
and also makes High V IN /Low V OUT operation possible. The
MIC2164/-2/-3/C controllers utilizes an architecture which is
adaptive T ON ripple controlled. A UVLO feature is provided to
ensure proper operation under power-sag conditions to
prevent the external power MOSFET from overheating. A soft
start feature is provided to reduce the inrush current.
Foldback current limit and “hiccup” mode short-circuit
protection ensure FET and load protection.
