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.

NOTES:
1. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets; molding compounds/die attach materials and NiPdAu plate -
e4 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin
plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
