NCP718BMT500TBG

The NCP718BMT500TBG is ON Semiconductor’s NCP718 family buck (step-down) DC-DC converter. It is designed to deliver up to about 500 mA to a regulated output from a higher input voltage, making it suitable for compact, power-sensitive electronics.
Key points
- Type: High-efficiency switching regulator (buck) with current‑mode control.
- Output: Approx. 500 mA capability; externally set the output voltage with feedback resistors.
- Package: Small, tape-and-reel (TBG) packaging for automated assembly.
- Features: Enable control, soft-start, and protection features (overcurrent/short‑circuit protection and thermal shutdown).
- External components: Requires an inductor, catch diode (for non-synchronous designs) or suitable synchronous setup, input/output capacitors, and feedback network.
- Applications: Portable/mobile devices, wearables, embedded systems, and other compact power‑sensitive electronics.
Note: For exact electrical specifications (input range, efficiency, accurate output voltages, pinout, and recommended external components), consult the latest NCP718BMT500TBG datasheet.

8-pin MSOP (MSOP-8) small-outline package.

8 pins. It is a buck (step-down) DC-DC switching regulator device used to convert a higher input voltage to a regulated lower output, with typical pins for input, switch, ground, feedback, enable, and related control signals. External inductor, diode (or internal path), and capacitors are typically required.

- Manufacturer: ON Semiconductor (Onsemi).
- What kind of company: An American multinational semiconductor company that designs and manufactures power management, analog, and discrete ICs for automotive, industrial, and consumer electronics.

Application areas: 500 mA fixed-output buck regulator for low-voltage rails; ideal as a point-of-load regulator in battery-powered and space-constrained systems. Used in portable devices and embedded systems, consumer electronics (set-top boxes, TVs, audio gear, wearables), networking/telecom equipment, and automotive/industrial electronics requiring compact, efficient DC-DC conversion.
