Technical Specifications

The RT3607BCGQW operates with an input voltage range of 4.5V to 25V. The output voltage is adjustable via external resistors. It features internal soft-start circuitry to limit inrush current during startup. The switching frequency is adjustable, allowing for optimization of efficiency and component size. The controller incorporates comprehensive protection features, including overcurrent protection (OCP), overvoltage protection (OVP), and under-voltage lockout (UVLO). The package is a thermally enhanced QFN package, providing excellent heat dissipation. It utilizes a current mode control architecture for fast transient response and stable operation. External components, such as MOSFETs and inductors, are required to complete the buck converter circuit. The operating temperature range is -40°C to +85°C.
