ISL6520  
FN9009  
Rev 6.00  
Apr 3, 2007  
Single Synchronous Buck Pulse-Width Modulation (PWM) Controller  
The ISL6520 makes simple work out of implementing a  
complete control and protection scheme for a DC/DC  
stepdown converter. Designed to drive N-Channel  
MOSFETs in a synchronous buck topology, the ISL6520  
integrates the control, output adjustment, monitoring and  
protection functions into a single 8 Lead package.  
Features  
• Operates from +5V Input  
• 0.8V to V Output Range  
IN  
- 0.8V Internal Reference  
- ±1.5% Over Line Voltage and Temperature  
The ISL6520 provides simple, single feedback loop, voltage-  
mode control with fast transient response. The output  
voltage can be precisely regulated to as low as 0.8V, with a  
maximum tolerance of 1.5% over-temperature and line  
voltage variations. A fixed frequency oscillator reduces  
design complexity, while balancing typical application cost  
and efficiency.  
• Drives N-Channel MOSFETs  
• Simple Single-Loop Control Design  
- Voltage-Mode PWM Control  
• Fast Transient Response  
- High-Bandwidth Error Amplifier  
- Full 0% to 100% Duty Cycle  
The error amplifier features a 15MHz gain-bandwidth  
product and 8V/s slew rate which enables high converter  
bandwidth for fast transient performance. The resulting  
PWM duty cycles range from 0% to 100%.  
• Lossless, Programmable Over-Current Protection  
- Uses Upper MOSFET’s r  
DS(on)  
• Small Converter Size  
- 300kHz Fixed Frequency Oscillator  
- Internal Soft Start  
Protection from over-current conditions is provided by  
monitoring the r  
of the upper MOSFET to inhibit PWM  
DS(ON)  
- 8 Ld SOIC or 16Ld 4mmx4mm QFN  
operation appropriately. This approach simplifies the  
implementation and improves efficiency by eliminating the  
need for a current sense resistor.  
• QFN Package:  
- Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat  
No Leads - Package Outline  
Ordering Information  
- Near Chip Scale Package footprint, which improves  
PCB efficiency and has a thinner profile

NOTE: Intersil Pb-free plus anneal products employ special Pb-free  
material sets; molding compounds/die attach materials and 100% matte  
tin plate termination finish, which are 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.
