7Semi Step-Up Miniature DC-DC Converter 3.3V Output Module

The 7Semi Step-Up Mini DC-DC Converter is a compact power module designed to convert low input voltages into a stable fixed 3.3V output. Supporting an input voltage range of 0.65V to 6.0V, the module is suitable for powering low-voltage embedded electronics, battery-operated devices, and applications requiring reliable voltage boosting from low-power sources. The miniature design integrates a Murata MYRBP330080W21RD inductor and control IC into a single compact package, reducing board space requirements.

The converter requires only two external capacitors to create a stable step-up power supply, helping simplify circuit design while reducing wiring complexity and electrical noise. It utilizes PWM switching control for efficient power conversion and incorporates a CL Discharge Function that rapidly discharges the output capacitor during standby mode, helping prevent application malfunctions.

Designed for compact electronic systems, the module is suitable for real-time clocks (RTC), battery-powered equipment, and low-voltage embedded applications. Its combination of a wide input voltage range, fixed regulated output, and integrated inductor makes it a practical solution where space-saving and efficient power conversion are important design considerations.
