DATASHEET  
ISL6545, ISL6545A  
5V or 12V Single Synchronous Buck Pulse-Width Modulation (PWM) Controller  
FN6305  
Rev 7.00  
October 7, 2015  
The ISL6545, ISL6545A makes simple work out of  
implementing a complete control and protection scheme for a  
Features  
• Operates from +5V or +12V Supply Voltage (for bias)  
DC/DC stepdown converter driving N-Channel MOSFETs in a  
synchronous buck topology. Since it can work with either 5V or  
12V supplies, this one IC can be used in a wide variety of  
applications within a system. The ISL6545, ISL6545A  
(hereafter referred to as “ISL6545x”, except as needed)  
integrates the control, gate drivers, output adjustment,  
monitoring and protection functions into a single 8 Ld SOIC or  
10 Ld DFN package.  
- 1.0V to 12V V Input Range (up to 20V possible with  
IN  
restrictions; see Input Voltage Considerations)  
- 0.6V to V Output Range  
IN  
- Integrated Gate Drivers use V  
(5V to 12V)  
CC  
- 0.6V Internal Reference; ±1.0% tolerance  
• Simple Single-Loop Control Design  
- Voltage-Mode PWM Control  
The ISL6545x provides single feedback loop, voltage-mode  
control with fast transient response. The output voltage can be  
precisely regulated to as low as 0.6V, with a maximum  
tolerance of ±1.0% over-temperature and line voltage  
variations. A selectable fixed frequency oscillator (ISL6545 for  
300kHz; ISL6545A for 600kHz) reduces design complexity,  
while balancing typical application cost and efficiency.  
- Drives N-Channel MOSFETs  
- Traditional Dual Edge Modulator  
• Fast Transient Response  
- High-Bandwidth Error Amplifier  
- Full 0% to 100% Duty Cycle  
• Lossless, Programmable Overcurrent Protection  
- Uses Lower MOSFET’s r  
DS(ON)  
The error amplifier features a 20MHz gain-bandwidth  
product and 9V/µs slew rate which enables high converter  
bandwidth for fast transient performance. The resulting  
PWM duty cycles range from 0% to 100%.  
• Small Converter Size in 8 Ld SOIC or 10 Ld DFN  
- 300kHz or 600kHz Fixed Frequency Oscillator  
- Fixed Internal Soft-Start, Capable into a Pre-biased  
Load  
Protection from overcurrent conditions is provided by  
- Integrated Boot Diode  
monitoring the r  
of the lower MOSFET to inhibit PWM  
DS(ON)  
- Enable/Shutdown Function on COMP/SD Pin  
- Output Current Sourcing and Sinking  
operation appropriately. This approach simplifies the  
implementation and improves efficiency by eliminating the  
need for a current sense resistor.  
• Pb-Free (RoHS Compliant)  
Pinout  
Applications
