The ZL2102 is an integrated digital power regulator with auto

compensation and power management functions in a small

package, resulting in a flexible and integrated solution, which

can be configured using the PowerNavigator? graphical user

interface. This synchronous buck converter operates from a

4.5V to 14V input supply and provides from 0.54V to 5.5V

output voltage at up to 6A.

The ZL2102 can be configured for most applications using only

hardware pin straps to adjust switching frequency, output

voltage, UVLO, soft-start ramp/delay settings, sequencing

options, and SMBus address. For more advanced

configurations, the ZL2102 supports over 70 PMBus

commands. Output voltage/current is factory calibrated.

Internal synchronous power MOSFETs enable the ZL2102 to

deliver continuous loads up to 6A with high efficiency. An

internal Schottky bootstrap diode reduces discrete component

count. The ZL2102 also supports phase spreading to reduce

system input capacitance.

The ZL2102 uses the SMBus? with PMBus? protocol for

communication with a host controller and the Intersil's

proprietary Digital-DC? bus for interoperability between other

Intersil devices.
