The ZTP7193Y is an electronic part manufactured by ZILLTEK and is a DC-DC Converter. It is constructed with TSOT23-6L packaging and is compliant with RoHS regulations. It is a step-down, synchronous, DC-DC converter that can deliver a constant current of up to 3A output. Its features include under-voltage lockout, programmable current limit, and a low-noise operation with an integrated, high-speed, low-side MOSFET. It is also designed to provide a low quiescent current of typically 7.5µA for a 5V input. The part operates from an input voltage of 4.5V to 17V and provides an adjustable output voltage range of 0.8V to 5V. The thermal shutdown protection, cycle-by-cycle current limit and hiccup mode over current protect the part from any damage due to overloads of current. The ZTP7193Y can be used in applications such as personal media players, eBook Readers, low-power logic power, and cellular handsets.
