RM517 Series
0.3V Ultra-low Output Voltage 300mA Buck DC/DC Module
-
Description
The RM517 is a CMOS-based low-voltage step-down DC/DC module that achieves high efficiency by ultralow quiescent current (IQ = 0.3 µA) and VFM (maximum switching frequency of 1 MHz) control. Since the RM517 has a built-in inductor and the package is 3.0 (mm) x 2.4 (mm) x 0.8 (mm), QFN2430-8, it is suitable for high density mounting on board.
Key Benefits
- A built-in thin inductor simplifies the board design and dedicates to miniaturize the system.
- An ultra-low quiescent current (IQ = 0.3 µA) and high efficiency at all output current range.
- Low output voltage range (0.3 V to 1.2 V) contributes to low power drive of the system.
- Due to a built-in inductor, the number of external components can be reduced, and the purchasing risk such as EOL can be reduced.
