ZL2004-01  
Adaptive Digital DC/DC Controller with Current Sharing  
FN6847  
Rev 2.00  
May 23, 2011  
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.  
Features  
• Power Conversion  
• Efficient synchronous buck controller  
• ± 0.2% VOUT set-point accuracy  
• 8.0V to 10.0V input range  
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.  
• 0.9V to 1.1V output range  
• Adaptive performance optimization algorithms  
• Fast load transient response  
• Active current sharing  
• DCR current sensing with digitally adjustable current sense  
range  
• RoHS compliant (5mmx5mm) QFN package  
• Power Management  
Related Literature  
• See FN6846, ZL2004 “Adaptive Digital DC-DC Controller  
with Current Sharing”  
• Digital soft-start/stop  
• Precision delay and ramp-up  
• Power-good/enable  
• Voltage tracking, sequencing and margining  
• Voltage/current/temperature monitoring  
• SMBus communication (PMBus compliant)  
• Output voltage and current protection  
• Internal non-volatile memory (NVM)  
Applications  
• Servers/storage equipment  
• Telecom/datacom equipment  
• Power supplies (memory, DSP, ASIC, FPGA)
