Datasheet Intersil ZL2106

6A Digital-DC Synchronous Step-Down DC/DC Converter
ZL2106 Features The ZL2106 is a digital power conversion and management IC
that combines an integrated synchronous step-down DC/DC
converter with key power management functions in a small
package, resulting in a flexible and integrated solution. Integrated MOSFET switches The ZL2106 can provide an output voltage from 0.54V to 5.5V
(with margin) from an input voltage between 4.5V and 14V.
Internal low rDS(ON) synchronous power MOSFETs enable the
ZL2106 to deliver continuous loads up to 6A with high
efficiency. An internal Schottky bootstrap diode reduces
discrete component count. The ZL2106 also supports phase
spreading to reduce system input capacitance.
Power management features such as digital soft-start delay
and ramp, sequencing, tracking, and margining can be
configured by simple pin-strapping or through an on-chip serial
port. The ZL2106 uses the PMBusв„ў protocol for
communication with a host controller and the Digital-DC bus
for interoperability between other Zilker Labs devices. 6A continuous output current ±1% output voltage accuracy Snapshot™ parametric capture I2C/SMBus interface, PMBus compatible Internal non-volatile memory (NVM) Applications Telecom, Networking, Storage equipment Test and Measurement equipment Industrial control equipment 5V and 12V distributed power systems Related Literature AN1468 “ZL2106EVAL1Z Evaluation Board”, USB Adapter
