Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9142F51DER-G

The XC9142F51DER-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 0.3Oc N-channel driver and a 0.3Oc P-channel switching transistor. The device can start functioning 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 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 XC9142F51DER-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.
