Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9235C30CMR-G

The XC9235C30CMR-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It features a built-in 600mA driver transistor with a low on-resistance of 0.42Oc for the P-channel and 0.52Oc for the N-channel, allowing for efficient operation. The input voltage range is from 2.0V to 6.0V, with a fixed output voltage of 3.0V and an accuracy of ±2.0%. The device supports both PWM control and automatic PWM/PFM switching modes, providing flexibility for various load conditions. It operates at selectable oscillation frequencies of 1.2MHz or 3.0MHz, which can be tailored to specific application requirements. The XC9235C30CMR-G also includes features such as a soft start function, current limiting, and an under-voltage lockout (UVLO) function to enhance reliability. The product is available in a compact SOT-25 package, making it suitable for space-constrained applications like smartphones, portable devices, and digital cameras.
