The BL8531CC3TR30 with DC-DC Converters SOT89-3 RoHS manufactured by Belling is a surface mount, non-isolated, constant frequency, current-mode, step-down converter. It is specifically designed to provide a small, low cost power solution for handheld devices and other applications. The device operates over a wide input voltage range and offers excellent VOUT accuracy using only a few external components. It features a typical switching frequency of 2MHz and an adjustable output voltage that can be set as low as 0.8V. The converter also features a low shutdown current and an integrated soft-start for reduced inrush current during startup. The device operates in a 4-pin SOT89-3 package and is RoHS compliant.
