Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9142F42C0R-G

The XC9142F42C0R-G is a synchronous step-up DC/DC converter capable of delivering up to 0.8A output current. It operates efficiently with a built-in N-channel driver and P-channel switching transistor, featuring an ON resistance of 0.3Oc. The device can start with an input voltage as low as 0.9V to produce a stable output voltage of 3.3V under a 100Oc load, making it suitable for portable applications powered by single alkaline or nickel-metal hydride batteries. The output voltage is adjustable from 1.8V to 5.5V in 0.1V increments, and the device supports oscillation frequencies of either 1.2MHz or 3.0MHz, allowing for flexibility in design. It includes various operational modes, such as PWM and PWM/PFM control, and features protection circuits for over-current and output short-circuit conditions. The XC9142F42C0R-G is designed for a wide range of applications, including portable and wearable devices, and operates within an ambient temperature range of -40¬8C to 85¬8C. It is packaged in a compact SOT-25 format and is compliant with EU RoHS standards.
