DATASHEET 6A Digital Integrated Synchronous Step-Down DC/DC
Regulator with Auto Compensation
ZL2102 Features 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 PowerNavigatorв„ў 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. Integrated MOSFET switches 6A continuous output current Adjustable 0.54V to 5.5V output range 4.5V to 14V input range Up to 90% efficiency 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 SMBusв„ў with PMBusв„ў protocol for
communication with a host controller and the Intersil's
proprietary Digital-DCв„ў bus for interoperability between other
Intersil devices.
