The ZL2101 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 ZL2101 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

ZL2101 to deliver continuous loads up to 6A with high efficiency.

An internal Schottky bootstrap diode reduces discrete

component count. The ZL2101 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

ZL2101 uses the PMBus™ protocol for communication with a

host controller and the Digital-DC bus for interoperability

between other Zilker Labs devices.
