Adaptive Digital DC/DC Controller with Current Sharing
ZL2004-01
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.
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 PMBus™-compliant ZL2004-01 uses the SMBus™ serial
interface for communication with other Digital-DC products or a
host controller.
