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. Zilker Labs Digital-DC™ technology enables unparalleled power management integration while delivering industry-leading performance in a tiny footprint.

The ZL2106 can provide an output voltage from 0.54 V to 5.5 V (with margin) from an input voltage between 4.5 V and 14 V. Internal low R_DS(ON) synchronous power MOSFETs enable the ZL2106 to deliver continuous loads up to 6 A 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 softstart delay and ramp, sequencing, tracking, and margining can be configured by simple pinstrapping 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.
