General Description
The MIC23163/4 is a high-efficiency, 4MHz, 2A,
synchronous buck regulator with HyperLight Load
®
(HLL)
mode and maximum 100% duty cycle. HLL provides very-
high efficiency at light loads and ultra-fast transient
response which makes the MIC23163/4 perfectly suited for
supplying processor core voltages. An additional benefit of
this proprietary architecture is very low output ripple
voltage throughout the entire load range with the use of
small output capacitors. The tiny 2.0mm × 2.0mm DFN
package saves precious board space and requires only
three external components.
The MIC23163/4 is designed for use with a very small
0.47µH inductor and 10µF output capacitor that enables a
total solution size, less than 1mm height.
The MIC23163/4 has a very low quiescent current of 33µA
and achieves as high as 85% efficiency at 1mA. At higher
loads, the MIC23163/4 provides a constant switching
frequency around 4MHz while achieving peak efficiencies
up to 93%. The MIC23164 incorporates an active
discharge feature that switches an 180 FET to ground to
discharge the output when the part is disabled.
The MIC23163/4 is available in 10-pin 2.0mm × 2.0mm
DFN
package with an operating junction temperature
range from 40°C to +125°C.

Pin Description
Pin Number Pin Name Pin Function
1 SW
Switch (Output): Internal power MOSFET output switches. Disable pull down 180Ω
(MIC23164 only).
2 EN
Enable (Input): Logic high enables operation of the regulator. Logic low will shut down the
device. Do not leave floating.
3 FB Feedback: Connect a resistor divider from the output to ground to set the output voltage.
4 NC Not Internally Connected.
5 PG
Power Good: Open drain output for the power good indicator. Use a pull-up resistor from this pin
to a voltage source to detect a power good condition.
6 SS
Soft Start: Place a capacitor from this pin to ground to program the soft start time. Do not leave
floating, 100pF minimum C
SS
is required.
7 AGND
Analog Ground: Connect to central ground point where all high-current paths meet (C

8 AVIN Analog Input Voltage: Connect a capacitor to ground to decouple the noise.
9 PVIN Power Input Voltage: Connect a capacitor to PGND to decouple the noise.
10 PGND Power Ground.
