May 23, 2011 Adaptive Digital DC/DC Controller with Current Sharing Features The ZL2004-01 is specialized version of the ZL2004 DC/DC
controller that has been optimized for high output accuracy
within a given set of operating conditions. The ZL2004-01 is
otherwise identical to the ZL2004 in features and
functionality. The ZL2004-01 has been optimized for use with
the ZL1505 MOSFET driver and discrete MOSFETs. Power Conversion Efficient synchronous buck controller В± 0.2% VOUT set-point accuracy 8.0V to 10.0V input range The ZL2004-01 integrates a proprietary Digital-DC
communication bus for current sharing and inter device
communication. Adaptive algorithms improve light load
efficiency. All operating features can be configured by simple
pin-strap selection, resistor selection or through the on-board
serial port. The PMBusв„ў-compliant ZL2004-01 uses the
SMBusв„ў serial interface for communication with other DigitalDC products or a host controller. 0.9V to 1.1V output range Adaptive performance optimization algorithms Fast load transient response Active current sharing DCR current sensing with digitally adjustable current sense
