ZL2101ALAF

The ZL2101ALAF is a 6A digital converter with auto compensation and integrated power management 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 ZL2101ALAF 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 ZL2101ALAF to deliver continuous loads up to 6A with high efficiency. An internal Schottky bootstrap diode reduces discrete component count. The ZL2101ALAF 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 ZL2101ALAF uses the PMBus™ protocol for communication with a host controller and the Digital-DC bus for interoperability between other Zilker Labs devices.
