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.

NOTES:
8. All voltages are measured with respect to SGND.
9. JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379.
10. For JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications VDD = 8.6 V, VOUT = 1.0 V, TA = 0°C to +65°C unless otherwise noted. Typical values are at TA = +25°C. The
following specifications describe the ZL2004-01 electrical specifications that differ from the ZL2004. Please refer to the ZL2004 data sheet for the full
operating specification limits for the remaining functions not described herein. Boldface limits apply over the operating temperature range, 0°C to
+65°C.
