Renesas Electronics Corporation High Efficiency Buck-boost Regulators ISL91107IRTNZ-T

The ISL91107 and ISL91107IR are highly-integrated buck-boost switching regulators that accept input voltages either above or below the regulated output voltage. Unlike other buck-boost regulators, these regulators automatically transition between operating modes without significant output disturbance.
These devices are capable of delivering up to 2A of output current (PVIN = 2.8V, V_OUT = 3.3V) and provide excellent efficiency due to their fully synchronous 4-switch architecture. No-load quiescent current of only 45µA also optimizes efficiency under light-load conditions.
The ISL91107 and ISL91107IR are designed for standalone applications and support 3.3V fixed output voltages 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.
The ISL91107 and ISL91107IR require only a single inductor and very few external components. Power supply solution size is minimized by their 2.5MHz switching frequency, allowing small size external components.
The ISL91107IR is available in a 3x4 20 Ld TQFN package and the ISL91107 is available in a 2.15mmx1.51mm WLCSP package.
