Additional Details:

The XC9236A18CMR operates at a high switching frequency, further contributing to the reduction in external component size. The device also includes soft-start circuitry to limit inrush current during startup. The specific output voltage is determined by the “18” in the part number, which likely indicates 1.8V, however datasheet verification is recommended for precise voltage specification. The device is RoHS compliant and halogen-free, making it suitable for environmentally conscious applications. Detailed specifications are available in the Torex Semiconductor datasheet for this product.
