6A Low Quiescent Current High Efficiency Synchronous Buck Regulator  
The ISL8016 is a high efficiency, monolithic, synchronous  
Features  
step-down DC/DC converter that can deliver up to 6A  
continuous output current from a 2.7V to 5.5V input supply.  
• High Efficiency Synchronous Buck Regulator with up to 97%  
Efficiency  
The output voltage is adjustable from 0.6V to V . With an  
IN  
adjustable current limit, reverse current protection, pre-bias  
start and over temperature protection the ISL8016 offers a  
highly robust power solution. It uses current control  
architecture to deliver fast transient response and excellent  
loop stability.  
• 1% Reference Accuracy Over-Temperature/Load/Line  
• Fixed Output Voltage Option  
• ±10% Output Voltage Margining  
• Adjustable Current Limit  
The ISL8016 integrates a pair of low ON-resistance P-Channel  
and N-Channel internal MOSFETs to maximize efficiency and  
minimize external component count. 100% duty-cycle  
operation allows less than 200mV dropout at 6A output  
current. Adjustable frequency and synchronization allow the  
ISL8016 to be used in applications requiring low noise.  
Paralleling capability with phase interleaving allows the IC to  
support >6A output current while offering reduced input and  
output noise.  
• Current Sharing Capable  
• Start-up with Pre-Biased Output  
• Internal Soft-Start - 1ms or Adjustable, Internal/External  
Compensation  
• Soft-Stop Output Discharge During Disabled  
• Adjustable Frequency from 500kHz to 4MHz - Default at  
1MHz  
• External Synchronization up to 4MHz - Master to Slave Phase  
Shifting Capability  
The ISL8016 can be configured for discontinuous or forced  
continuous operation at light load. Forced continuous operation  
reduces noise and RF interference while discontinuous mode  
provides high efficiency by reducing switching losses at light  
loads.  
• Peak current limiting, Hiccup Mode Short Circuit Protection  
and Over-Temperature Protection‘  
Applications  
• DC/DC POL Modules  
The ISL8016 is offered in a space saving 20 Ld 3x4 QFN lead  
free package with exposed pad lead frames for excellent  
thermal performance. The complete converter occupies less  
• µC/µP, FPGA and DSP Power  
• Plug-in DC/DC Modules for Routers and Switchers  
• Portable Instruments
