Adaptive Digital DC-DC Controller with Current Sharing
Description
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
the ZL2004 in features and functionality.
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.
