10A, High Efficiency DC/DC Module  
Features  
The ISL8201M is a 20V, 10A output current, variable output  
step-down power supply. Included in the 15mmx15mm  
package is a high performance PWM controller switching at  
600kHz, power MOSFETs, an inductor, and all the passive  
components required for complete DC/DC power solution.  
The ISL8201M operates over an input voltage range of 1V to  
20V and supports an output voltage range of 0.6V to 5V,  
which is set by a single dividing resistor. This high efficiency  
power module is capable of delivering 10A (17A peak) output  
with up to 95% efficiency, needing no heat sinks or airflow to  
meet power specifications. Only bulk input and output  
capacitors are needed to finish the design. Utilizing  
voltage-mode control, the output voltage can be precisely  
regulated to as low as 0.6V with up to ±1% output voltage  
regulation. The ISL8201M also features internal  
• Complete Switch Mode Power Supply  
• Bias Voltage Range from +4.5 to +14.4V  
- Wide Input Voltage Range from 1V up to 20V (see  
“Input Voltage Considerations” on page 11)  
• 10A DC Output Current, 17A Peak Output Current  
• Adjustable +0.6V to +5V Output Range  
• Up to 95% Efficiency  
• Simple Voltage Mode Control  
• Fixed 600kHz Switching Frequency  
• Fast Transient Response  
• Enable Function Option  
• Pre-biased Output Start-up Capability  
• Internal Soft-Start  
compensation, internal soft-start, auto-recovery overcurrent  
protection, an enable option, and pre-biased output start-up  
capability.  
• Overcurrent Protection by Low-Side MOSFET rDS(ON)  
Sensing (Non-Latching, Auto-Recovery)  
The ISL8201M is packaged in a thermally enhanced, compact  
(15mmx15mm) and low profile (3.5mm) over-molded QFN  
Package Module suitable for automated assembly by  
standard surface mount equipment. The ISL8201M is Pb-free  
and RoHS compliant.

NOTE: These Intersil Pb-free plastic packaged products employ  
special Pb-free material sets, molding compounds/die attach  
materials, and 100% matte tin plate plus anneal (e3 termination  
finish, which is 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.  
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
