Step-Up Regulator with 4A Integrated Switch  
ISL97656  
Features  
The ISL97656 is a high frequency, high efficiency current  
mode control non-synchronous step-up voltage regulator  
operated at constant PMW switching frequency. It has an  
internal 4.0A, 120mΩ Low side MOSFET and can deliver high  
output current and efficiency over 90%. The selectable 640kHz  
and 1.22MHz switching frequency allows use of smaller  
inductor and faster transient response. An external  
compensation pin gives the user flexibility in setting frequency  
compensation allowing the use of low ESR ceramic output  
capacitors.  
• 4.0A, Low r Integrated Low Side MOSFET  
DS(ON)  
• +2.2V to +6.0V Operating Input Voltage Range  
• +1.1*VIN to +24V Output Voltage Range  
• 640kHz or 1.22MHz Switching Frequency  
• Higher Efficiency and Better Thermal Performance  
• Adjustable Soft-Start  
• Internal Thermal Protection  
• 0.8mm Maximum Height 10 Ld TDFN Package  
• Pb-Free (RoHS Compliant)  
When in shut down mode, ISL97656 draws current <1µA and  
can operate at as low as 2.2V input. These features along with  
higher switching frequency allows use of tiny external  
components and makes it an ideal device for portable  
equipment and TFT-LCD displays.  
• Halogen Free  
Applications  
• Portable Equipment, Digital Cameras  
• TFT-LCD Displays, DSL Modems  
• PCMCIA Cards, GSM/CDMA Phones  
The ISL97656 is available in a 10 Ld TDFN package with a  
maximum height of 1.1mm. The device is specified for  
operation over the full -40°C to +85°C temperature range.

2. 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.
