Description
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- DC? technology enables
unparalleled power management integration while
delivering industry-leading performance in a tiny
footprint.
The ZL2105 can provide an output voltage from
Features
Power Conversion
? High efficiency
? 3 A continuous output current
? Integrated MOSFET switches
? 4.5 V to 14 V input range
? 0.54 V to 5.5 V output range (with margin)
? ±1% output voltage accuracy
? 200 kHz to 2 MHz switching frequency
? Supports phase spreading
? Small footprint (6 x 6 mm QFN package)
Power Management
0.6 V to 5.5 V from an input voltage between 4.5 V
and 14 V. Internal 4.5 A low R DS(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 features such as digital soft-

PMBus compatible
start delay and ramp, sequencing, tracking, and
margining can be configured by simple pin-
strapping or through an on-chip serial port. The
ZL2105 uses standard PMBus? protocol for
communicating with other devices to provide
intelligent system power management.
