Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9235C1DCER-G

The XC9235C1DCER-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It 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 operating voltage range is from 2.0V to 6.0V, with a fixed output voltage available from 0.8V to 4.0V in 0.05V increments, and an adjustable output voltage option starting from 0.9V using external resistors. This regulator can deliver an output current of up to 600mA and offers selectable oscillation frequencies of 1.2MHz or 3.0MHz, depending on the application requirements. The XC9235C1DCER-G operates in PWM control mode, providing fast response and low ripple across varying load conditions. It includes features such as a built-in soft start, current limiting, and an under-voltage lockout (UVLO) function to enhance reliability. The device is suitable for various applications, including mobile phones, Bluetooth devices, portable game consoles, and digital cameras. It is available in multiple package options, including SOT-25 and USP-6C, and is compliant with EU RoHS standards.
