MIC2166
Adaptive On-Time DC-DC Controller
Hyper Speed Control? Family
General Description
Features
The Micrel MIC2166 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 MIC2166 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.
MIC2166 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 Control? architecture enables
ultra-fast transient response while reducing the output
capacitance and also makes High V IN /Low V OUT operation
possible.
A UVLO feature is provided to ensure proper operation
under power-sag conditions to prevent the external power
MOSFET from over heating. Also, a soft-start feature is
provided to reduce the inrush current. Short current
sensing on the bottom MOSFET with hiccup mode current

Hyper Speed Control? architecture enables
- High delta V operation (V IN =28V and V OUT =0.8V)
- Small output capacitance
Built-in 5V regulator for single-supply operation
Any Capacitor TM stable
- Zero ESR to high ESR
Power-Good (PGOOD) output
Input voltage range: 4.5V to 28V
5 μ A typical shutdown current
25A output current drive capability
Adjustable output from 0.8V to 5.5V with ±1% FB
accuracy
600kHz switching frequency
Internal 5ms digital soft-start
Thermal-shutdown and hiccup current-limit protection
No external current-sense resistor required
Safe start-up into pre-biased loads
10-pin MSOP ePad package
limiting ensures protection in case of an output short
circuit. Further, the MIC2166 includes an EN pin to shut
down the converter and a Power-Good (PGOOD) pin to
allow simple sequencing.
? –40 ° C to +125 ° C junction temperature range
Applications
? Set-top box, gateways, routers and DSL modems
The MIC2166 is available in a 10 pin MSOP ePad package
with a junction operating temperature ranging from –40 ° C
to +125 ° C. All support documentation can be found on
