DESCRIPTION:

The ATI2202 is a robust 340kHz fixed-frequency PWM synchronous step-down regulator, designed for seamless operation within a voltage range of 4.75V to 18V. Offering an adjustable output voltage spanning from 0.923V to 0.9×VPS and capable of delivering up to 2A output current, it stands as a cornerstone for efficient and reliable power management.
Employing a current mode control mechanism, it ensures a swift transient response and incorporates cycle-by-cycle overcurrent protection. Featuring the integration of two MOSFET switches with a low turn-on resistance of 0.13Ω, the ATI2202 achieves high efficiency of up to an impressive 93% and mere 1μA typical shutdown current, making it an ideal choice for battery-powered systems.
To facilitate smooth power-on sequences, the ATI2202 includes adjustable soft start functionality, effectively mitigating inrush currents. Furthermore, it integrates over-temperature shutdown protection, adding an extra layer of security to safeguard both the regulator and connected components.
Encased in a thermally enhanced SOP-8 package with a heat sink solder pad underneath, the ATI2202 prioritizes effective heat dissipation. In full compliance with RoHS standards and boasting 100% lead (Pb) free composition, it aligns seamlessly with modern environmental regulations. The ATI2202 emerges as a versatile and reliable solution catering to diverse power regulation applications.
