DATASHEET  
ISL6341, ISL6341A, ISL6341B, ISL6341C  
5V or 12V Single Synchronous Buck Pulse-Width Modulation (PWM) Controller  
FN6538  
Rev 2.00  
Dec 2, 2008  
The ISL6341, ISL6341A, ISL6341B, ISL6341C makes  
simple work out of implementing a complete control and  
Features  
• Operates from +4.5V to 14.4V Supply Voltage (for Bias)  
protection scheme for a 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 family of  
IC’s can be used in a wide variety of applications within a  
system. It integrates the control, gate drivers, output  
adjustment, monitoring and protection functions into a single  
10 Ld Thin DFN package.  
- 1.5V to 12V V Input Range (Up to 20V is Possible with  
IN  
Restrictions; see “Input Voltage Considerations” on  
page 12)  
- 0.8V to ~V Output Range (Duty Cycle Limited)  
IN  
- Integrated Gate Drivers; LGATE Uses V  
(5V to 12V);  
CC  
UGATE Uses External Boot Diode to (5V to 12V)  
- 0.8V Internal Reference; ±0.8% Tolerance  
The ISL6341, ISL6341A, ISL6341B, ISL6341C (hereafter  
referred to as “ISL6341x”, except as needed) provides 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 ±0.8%  
• Simple Single-Loop Control Design  
- Traditional Dual Edge Modulator  
- Voltage-Mode PWM Control  
- Drives N-Channel MOSFETs  
over-temperature and line voltage variations. A fixed frequency  
oscillator and wide duty cycle range reduces design complexity,  
while balancing typical application cost and efficiency. The  
frequency, duty cycle and OCP response are the only  
differences among the ISL6341x versions. See Table 1.  
• Fast Transient Response  
- High-Bandwidth Error Amplifier  
- 0% to 85% Max Duty Cycle for ISL6341, ISL6341C  
- 0% to 75% Max Duty Cycle for ISL6341A, ISL6341B  
• Lossless, Programmable Overcurrent Protection  
Protection from overcurrent conditions is provided by  
- Uses Lower MOSFET’s r  
DS(ON)  
- Latch off mode (ISL6341, ISL6341B)  
monitoring the r  
of the lower MOSFET to inhibit PWM  
DS(ON)  
operation appropriately (see “Overcurrent Protection (OCP)”  
on page 8 for details). This approach simplifies the  
implementation and improves efficiency by eliminating the  
need for a current sense resistor. The output voltage is also  
monitored for undervoltage and overvoltage protection, in  
addition to monitoring for a PGOOD output.  
- Infinite Retry (Hiccup) Mode (ISL6341A)  
- Infinite Retry (Hiccup) Mode; no UVP (ISL6341C)  
• Output Voltage Monitoring  
- Undervoltage and Overvoltage Shutdown  
- PGOOD Output  
Ordering Information  
• Small Converter Size in 10 Ld 3x3 Thin DFN  
- 300kHz Fixed Oscillator (ISL6341, ISL6341C)  
- 600kHz Fixed Oscillator (ISL6341A, ISL6341B)
