6A Dual Synchronous Buck Regulator with Integrated MOSFETs  
The ISL65426 is a high efficiency dual output monolithic  
Features  
synchronous buck converter operating over an input  
voltage range of 3V to 5.5V. This single chip power solution  
provides two output voltages, which are selectable or  
externally adjustable from 1V to 80% of the supply voltage  
while delivering up to 6A of total output current. The two  
PWMs are synchronized 180° out-of-phase, reducing the  
RMS input current and ripple voltage.  
• High Efficiency: Up to 95%  
• Fixed Frequency: 1MHz  
• Operates From 3V to 5.5V Supply  
• ±1% Reference  
• Flexible Output Voltage Options  
- Programmable 2-Bit VID Input  
- Adjustable Output From 1V to 4.0V  
The ISL65426 switches at a fixed frequency of 1MHz and  
utilizes current-mode control with integrated compensation  
to minimize the size and number of external components  
and provide excellent transient response. The internal  
synchronous power switches are optimized for good  
thermal performance and high efficiency.  
• User-Partitioned Power Blocks  
• Ultra-Compact DC/DC Converter Design  
• PWMs Synchronized 180° Out-of-Phase  
• Independent Enable Inputs and System Enable  
• Stable All Ceramic Solutions  
A unique power block architecture allows partitioning of six  
1A blocks to support one of four configuration options. One  
master power block is associated with each synchronous  
converter channel. Four floating slave power blocks allow  
the user to assign them to either channel. Proper external  
configuration of the power blocks is verified internally prior  
to soft-start initialization.  
• Excellent Dynamic Response  
• Independent Output Digital Soft-Start  
• Power-Good Output Voltage Monitor  
• Thermal-Overload Protection  
• Overcurrent and Undervoltage Protection  
• Pb-Free (RoHS Compliant)  
Independent enable inputs allow for synchronization or  
sequencing soft-start intervals of the two converter  
channels. A third enable input allows additional sequencing  
for multi-input bias supply designs. Individual power-good  
indicators (PG1, PG2) signal when output voltage is within  
the regulation window.  
Applications  
• FPGA, CPLD, DSP, and CPU Core and I/O Voltages  
- Xilinx Spartan IIITM, Virtex IITM, Virtex II ProTM  
Virtex 4TM  
- Altera StratixTM, Stratix IITM, CycloneTM, Cyclone IITM  
- Actel FusionTM, LatticeSCTM, LatticeECTM  
,
The ISL65426 integrates protection for both synchronous  
buck regulator channels. The fault conditions include  
overcurrent, undervoltage, and IC thermal monitor.  
• Low-Voltage, High-Density Distributed Power Systems  
• Point-of-Load Regulation  
High integration contained in a thin Quad Flat No-lead  
(QFN) package makes the ISL65426 an ideal choice to  
power many of today’s small form factor applications. A  
single chip solution for large scale digital ICs, like field  
programmable gate arrays (FPGA), requiring separate core  
and I/O voltages.

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.
