Overview

The CN299-ISL9122A board is designed for optimized battery power supply in IoT applications. It enables quick evaluation of the ISL9001A low dropout linear regulator and the ISL9122A ultra-low quiescent current (IQ) buck-boost regulator. The ISL9122A's output voltage can be adjusted via the I²C interface, offering flexibility in design. This highly integrated, non-inverting buck-boost switching regulator can accept input voltages either above or below the regulated output voltage.

The CN299-ISL9122A provides a cost-effective solution for low-power applications that require seamless PWM/PFM transitions and efficient buck/boost voltage regulation. It is ideal for use cases where both step-up and step-down voltage capabilities are needed.
