概要
説明
The ZL2105 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 ZL2105 can provide an output voltage from 0. 6 V to 5. 5 V from an input voltage between 4. 5 V and 14 V. Internal 4. 5 A low RDS(ON) synchronous power MOSFETs enable the ZL2105 to deliver continuous loads up to 3 A with high efficiency, and an internal Schottky bootstrap diode further reduces discrete component count. The ZL2105 also supports phase spreading for reduced system 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 ZL2105 uses standard PMBus™ protocol for communicating with other devices to provide intelligent system power management.
