BL8022CB5TR is a DC-DC Converters SOT23-5 RoHS manufactured and released by Belling. It is an electronic component composed of PWM controller, high-accuracy on-chip reference, operational amplifier, current limit circuitry, and internal thermal shutdown circuitry. It is designed to provide up to 1.2A of current for DC-DC converters, enabling the conversion of input voltages from 2V to 5.5V to fixed output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, or 5.0V. This part is RoHS compliant and offers excellent performance and reliability with a near unity current-limit limit accuracy. It also comes with an integrated under-voltage lockout and soft-start function which helps to improve the system stability and efficiency.
