ZL2103

ZL2103 NOT RECOMMENDED FOR NEW DESIGNS RECOMMENDED REPLACEMENT PART ZL2102 3A Digital-DC Synchronous Step-Down DC/DC Converter DATASHEET FN6966 Rev 5.00 May 3, 2011 The ZL2103 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 ZL2103 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 ZL2103 to deliver continuous loads up to 3A with high efficiency. An internal Schottky bootstrap diode reduces discrete component count. The ZL2103 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 ZL2103 uses the PMBus™ protocol for communication with a host controller and the Digital-DC bus for interoperability between other Zilker Labs devices.
