High Efficiency Synchronous Boost Converter with 4.2A Switches and Output  
Disconnect  
The ISL91117 is a highly-integrated boost switching regulator  
Features  
for battery powered applications. The device provides a power  
supply solution for products using dual-cell or three-cell  
alkaline, NiCd or NiMH, or one-cell Li-ion or Li-polymer battery.  
• Input voltage range: 1.8V to 4.8V  
• Fixed 5V or adjustable output  
• Output current: up to 1.5A (PVIN = 3.3V, VOUT = 5V)  
• High efficiency: up to 96%  
This device is capable of delivering an output current of 1.5A  
with PVIN = 3.3V and VOUT = 5V. The use of a synchronous  
rectifier maximizes efficiency at high loads. No-load quiescent  
current of only 35µA optimizes efficiency under light-load  
conditions. Forced PWM and/or synchronization to an external  
clock may also be selected for noise sensitive applications.  
• 35µA quiescent current maximizes light-load efficiency  
• True input-output disconnect when disabled  
• 2.6MHz switching frequency minimizes external component  
size  
The ISL91117 is designed for standalone applications and  
supports 5V fixed output voltage or variable output voltages  
with an external resistor divider. Power supply solution size is  
minimized by a 2.34mm x 1.72mm WLCSP and a 2.6MHz  
switching frequency, which allows for the use of tiny,  
low-profile inductors and ceramic capacitors to minimize the  
size of the solution.  
• Selectable forced-PWM mode and external synchronization  
• Fully protected for short-circuit, over-temperature and  
undervoltage  
• Small 2.34mm x 1.72mm WLCSP  
Applications  
• Smart phones and tablets
