DATASHEET  
High Efficiency Buck-Boost Regulator with 4.2A Switches  
ISL91108  
Features  
The ISL91108 is a highly-integrated buck-boost switching  
regulator that accepts input voltages either above or below the  
regulated output voltage. Unlike other buck-boost regulators,  
this regulator automatically transitions between operating  
modes without significant output disturbance.  
• Accepts input voltages above or below regulated output  
voltage  
• Automatic and seamless transitions between buck and  
boost modes  
• Input voltage range: 1.8V to 5.5V  
This device is capable of delivering up to 2.7A of burst current  
• Output current: up to 1.6A DC (PVIN = 2.8V, V  
OUT  
= 3.3V)  
(PVIN = 3V, V  
= 3.3V), and provides excellent efficiency due  
OUT  
• Burst current: up to 2.7A (PVIN = 3V, V  
<600µs, t = 4.6ms)  
= 3.3V, t  
ON  
to its fully synchronous 4-switch architecture. No load  
quiescent current of only 27.5µA also optimizes efficiency  
under light-load conditions. Forced PWM and/or  
synchronization to an external clock may also be selected for  
noise sensitive applications.  
OUT  
• High efficiency: up to 95%  
• 27.5µA quiescent current maximizes light load efficiency  
• 2.6MHz switching frequency minimizes external component  
size  
The ISL91108 is designed for standalone applications and  
supports a 3.3V fixed output voltage or variable output  
voltages with an external resistor divider. Output voltages as  
low as 1V or as high as 5.2V are supported using an external  
resistor divider.  
• Selectable forced PWM mode and external synchronization  
• Fully protected for short-circuit, over-temperature, and  
undervoltage  
The ISL91108 requires only a single inductor and very few  
external components. Power supply solution size is minimized  
by a 2.34mmx1.72mm WLCSP and a 2.6MHz switching  
frequency, which further reduces the size of external  
components.  
• Small 2.34mm x 1.72mm WLCSP  
Applications  
• Smartphones and tablets  
• Wireless communication devices  
• 2G/3G/4G power amplifiers
