Data Sheet  
November 24, 2008  
FN9055.10  
Single Synchronous Buck Pulse-Width  
Modulation (PWM) Controller  
Features  
• Operates from 3.3V to 5V Input  
The ISL6526, ISL6526A make simple work out of  
• 0.8V to V Output Range  
IN  
- 0.8V Internal Reference  
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 ISL6526,  
ISL6526A integrate the control, output adjustment,  
monitoring and protection functions into a single package.  
- ±1.5% Over Load, Line Voltage and Temperature  
• Drives N-Channel MOSFETs  
• Simple Single-Loop Control Design  
- Voltage-Mode PWM Control  
The ISL6526, ISL6526A provide 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  
• Lossless, Programmable Overcurrent Protection  
- Uses Upper MOSFET’s r  
DS(on)  
The error amplifier features a 15MHz gain-bandwidth  
product and 6V/µs slew rate which enables high converter  
bandwidth for fast transient performance. The resulting  
PWM duty cycles range from 0% to 100%.  
• Converter can Source and Sink Current  
• Small Converter Size  
- Internal Fixed Frequency Oscillator  
-
-
ISL6526: 300kHz  
ISL6526A: 600kHz  
Protection from overcurrent conditions is provided by  
monitoring the r  
of the upper MOSFET to inhibit PWM  
DS(ON)  
• Internal Soft-Start  
operation appropriately. This approach simplifies the  
implementation and improves efficiency by eliminating the  
need for a current sense resistor.  
• 14 Ld SOIC or 16 Ld 5x5 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  
• Pb-Free (RoHS Compliant)  
Applications  
• Power Supplies for Microprocessors  
- PCs  
- Embedded Controllers  
• Subsystem Power Supplies  
- PCI/AGP/GTL+ Buses  
- ACPI Power Control  
- DDR SDRAM Bus Termination Supply  
• Cable Modems, Set-Top Boxes, and DSL Modems  
• DSP and Core Communications Processor Supplies  
• Memory Supplies  
• Personal Computer Peripherals  
• Industrial Power Supplies  
• 3.3V-Input DC/DC Regulators  
• Low-Voltage Distributed Power Supplies  
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
