ZL2004-01

Adaptive Digital DC-DC Controller with Current Sharing

Product Status: Mass Production

OVERVIEW

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 pinstrap 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.
