6A Digital Synchronous Step-Down DC/DC Converter with Auto Compensation
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.
