6A Digital Synchronous Step-Down DC/DC Converter
with Auto Compensation
ZL2101
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 r DS(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.
