The XD4069 with DC-DC Converters DIP-14 RoHS is a monolithic integrated circuit manufactured by XINLUDA. This circuit is used to step down a higher input voltage, typically +5V, to a lower output voltage, commonly +3.3V. The chip deals with voltage conversion using a buck regulator. Additionally, it offers high efficiency and is designed to operate with low ripple and noise. The XD4069 has a variety of features, such as an in-line current sense circuit, frequency compensation, active voltage limiting, short circuit protection, and thermal shutdown. This integrated circuit is a RoHS compliant DIP-14 package, and the operating temperature range is – 40 °C to 85 °C.
