The XC9142F33CMR-G is a 0.8A synchronous step-up DC/DC converter manufactured by Torex Semiconductor. It is a single-ended, single-channel device, which can be used to generate an output voltage of between 1.2 V and 5.5 V from an input voltage of up to 5.0 V. It features a quiescent current of 2 mA and a high switching frequency of up to 1 MHz, allowing for a compact design and high efficiency. The device is designed to have minimized EMI and reduce power dissipation, allowing for compact, power-efficient designs. The XC9142F33CMR-G also features a fast start-up time of 1 ms and a programmable soft-start time of up to 4ms. Additionally, the device comes with integrated protection circuits, such as output over-current protection, thermal shutdown and under-voltage lockout. The XC9142F33CMR-G is intended for use in industrial, healthcare, automotive, and consumer applications.
