The RT6208 is a highly efficient, monolithic synchronous step-down DC/DC converter designed to deliver exceptional performance across a wide range of applications. Capable of providing up to 100mA of output current from an input supply spanning 4.75V to 36V, the RT6208 offers a versatile and dependable solution for diverse power management needs. Notably, its standout feature is its remarkable efficiency, drawing only 25μA of typical supply current at no load while maintaining precise output voltage regulation. This ensures optimal efficiency across varying load conditions, rendering the RT6208 suitable for a broad spectrum of power supply requirements. Operating in Boundary Conduction Mode (BCM), the RT6208 boasts low quiescent current and an adjustable high-side peak current limit, further enhancing its efficiency and performance. This allows the RT6208 to maintain high efficiency over a wide range of load currents, providing consistent and reliable power delivery. Additionally, the inclusion of soft-start protection is a valuable feature, effectively eliminating input current surge during start-up, ensuring smooth and stable operation from the moment power is applied.Furthermore, the RT6208 offers a low current (3μA) shutdown mode, providing output disconnect functionality. This feature is particularly beneficial for battery-powered systems, enabling easy power management and contributing to extended battery life. The RT6208 is available in SOT-23-6 and SOT-23-8 packages. The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 85°C.
