6A Digital-DC Synchronous Step-Down DC/DC
Converter
ZL2106
The ZL2106 is an innovative 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.
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 r
DS(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 PMBus™
protocol for communication with a host controller and the
Digital-DC bus for interoperability between other Zilker
Labs devices.
