Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9235B15DER-G

The XC9235B15DER-G is a synchronous step-down DC/DC converter designed to provide a stable output voltage of 1.5V with a maximum output current of 600mA. It operates within an input voltage range of 2.0V to 6.0V and features a built-in P-channel MOS driver transistor with a resistance of 0.42Ω and an N-channel MOS switching transistor with a resistance of 0.52Ω. The device supports high efficiency, achieving up to 92% under typical conditions, and is optimized for use with ceramic capacitors. This regulator offers multiple control methods, including fixed PWM control, and is suitable for applications requiring low ripple and fast response across varying load conditions. The XC9235B15DER-G includes features such as a soft start function, current limiting, and an under-voltage lockout (UVLO) function to enhance reliability. It is available in various package options, including SOT-25, USP-6C, and WLP-5-03, making it versatile for different design requirements. The device is also compliant with EU RoHS standards, ensuring it meets environmental regulations.
