FN9083.2  
Single Synchronous Buck Pulse-Width  
Modulation (PWM) Controller  
Features  
• Operates from +5V Input  
The ISL6520B makes simple work out of implementing a  
complete control scheme for a DC-DC stepdown converter.  
Designed to drive N-channel MOSFETs in a synchronous  
buck topology, the ISL6520B integrates the control, output  
adjustment and monitoring functions into a single 8-Lead  
package.  
• 0.8V to V Output Range  
IN  
- 0.8V Internal Reference  
- ±1.5% Over Line Voltage and Temperature  
• Drives N-Channel MOSFETs  
• Simple Single-Loop Control Design  
- Voltage-Mode PWM Control  
The ISL6520B 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.  
• Fast Transient Response  
- High-Bandwidth Error Amplifier  
- Full 0% to 100% Duty Cycle  
• Small Converter Size  
- 300kHz Fixed Frequency Oscillator  
- Internal Soft Start  
The error amplifier features a 15MHz gain-bandwidth  
product and 8V/µs slew rate which enables high converter  
bandwidth for fast transient performance. The resulting PWM  
duty cycles range from 0% to 100%.  
- 8 Ld SOIC or 16Ld 4x4mm QFN  
• QFN Package:  
- Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat  
No Leads - Package Outline  
- Near Chip Scale Package footprint, which improves  
PCB efficiency and has a thinner profile
