The TC110303ECTTR is a step-up (boost) DC-DC switching controller from Quarktwin Technology Ltd. It is designed to deliver output currents up to 300mA with a typical efficiency of 84%. The device operates with input voltages ranging from 2.0V to 10.0V and guarantees start-up at a low voltage of 0.9V. It features a low supply current of 50¬µA at a switching frequency of 300kHz, which can be reduced to less than 0.5¬µA in shutdown mode. The controller supports programmable soft-start functionality and is housed in a compact 5-Pin SOT-23A package, making it suitable for applications in battery-operated systems, portable communicators, and positive LCD bias generators. The operating temperature range is specified from -40¬8C to +85¬8C, ensuring reliability in various environments.
