XC9259 Series is Not Recommended for New Designs. XC9259 Series ETR05041-003 COT Control, 1.0A Synchronous Step-Down DC/DC Converters ■GENERAL DESCRIPTION ☆GreenOperation-compatible The XC9259 series is a group of synchronous-rectification type DC/DC converters with a built-in P-channel MOS driver transistor and N-channel MOS switching transistor, designed to allow the use of ceramic capacitors. Output voltage is internally set in a range from 0.8V to 3.6V (accuracy: ±2.0%) increments of 0.05V. The device provides a high efficiency, stable power supply with an output current of 1.0A to be configured using only a coil and two capacitors connected externally. Oscillation frequency is set to 1.2MHz or 6.0MHz can be selected for suiting to your particular application.
