Torex Semiconductor, Ltd. DC DC Switching Controllers XC9502B095DR-G

The XC9502B095DR-G is a dual-channel DC/DC controller IC designed for step-up and step-down voltage regulation. It operates with a supply voltage range of 2.0V to 10.0V and can handle input voltages from 0.9V to 10.0V. The first output channel is a step-up converter with an adjustable output voltage range from 1.5V to 30V, while the second channel is a step-down converter with an output voltage range of 0.9V to 6.0V. The device features a typical efficiency of 83% for the step-up channel and 92% for the step-down channel, with a maximum output current of over 300mA and 1000mA, respectively. The XC9502B095DR-G supports PWM and PWM/PFM control methods, allowing for efficient operation across varying load conditions. It includes a soft-start feature to mitigate inrush currents and voltage overshoot during power-up. The device is packaged in a compact MSOP-10 or USP-10 format and is compliant with EU RoHS standards, making it suitable for environmentally conscious designs. This controller is ideal for applications such as portable devices, PDAs, and various power supply needs.
