Overview
Description
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. 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 PMBus™ protocol for communication with a host controller and the Digital-DC bus for interoperability between other Zilker Labs devices.
