ZL2004-01 February 18, 2009 Data Sheet FN6847.0 Adaptive Digital DC-DC Controller with Current Sharing Features Description Power Conversion 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 DigitalDC products or a host controller.
