ISL91107IRA-EVZ

The ISL91107IRA-EVZ is an evaluation board to evaluate ISL91107IRTAZ ADJ output voltage regulator IC. The ISL91107IR is a high efficiency buck-boost 4.1A switching regulator that accepts input voltages either above or below the regulated output voltage. This regulator automatically transitions between operating modes without significant output disturbance. The ISL91107IR is designed for standalone applications and 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. The ISL91107IR requires only a single inductor and very few external components. Power supply solution size is minimized by its 2.5MHz switching frequency, allowing small size external components. It is used in smart phones and tablet PCs and optical modules networking equipment.

• Automatic and seamless transitions between buck and boost modes
• Input voltage range from 1.8V to 5.5V
• High efficiency up to 96%
• 45µA quiescent current maximizes light load efficiency
• Selectable forced PWM mode
• Fully protected for short-circuit, over-temperature and undervoltage
