FN6851.2 3A Integrated Digital DC-DC Converter
Description Features The ZL2105 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.
Zilker Labs Digital-DCв„ў technology enables
unparalleled power management integration while
delivering industry-leading performance in a tiny
footprint. Power Conversion The ZL2105 can provide an output voltage from
0.6 V to 5.5 V from an input voltage between 4.5 V
and 14 V. Internal 4.5 A low RDS(ON) synchronous
power MOSFETs enable the ZL2105 to deliver
continuous loads up to 3 A with high efficiency,
and an internal Schottky bootstrap diode further
reduces discrete component count. The ZL2105
also supports phase spreading for reduced system
capacitance. Power Management Power management features such as digital softstart delay and ramp, sequencing, tracking, and
margining can be configured by simple pinstrapping or through an on-chip serial port. The …
