概要
Description
NCP718BMT500TBG is a compact 500 mA buck regulator IC from On Semiconductor, used to generate a stable lower voltage from a higher input in portable electronics.
Key features (typical):
- Integrated switching regulator with efficient power conversion
- External feedback or fixed output option to set Vout
- Enable pin for controlled power-on/off
- Protection features such as overcurrent and thermal shutdown
- RoHS-compliant, small surface-mount package (tape‑and‑reel option indicated by TBG)
Typical applications:
- handheld and battery-powered devices
- microcontroller and peripheral power rails
- charging circuits and portable electronics power management
Note:
- For exact electrical specs (input range, output voltage options, switching frequency, soft-start, UVLO, pinout), consult the official datasheet or supplier page.

Equivalent
Equivalent parts depend on the exact spec (output voltage/current and LDO vs. switching regulator) and packaging. NCP718BMT500TBG is an ON Semiconductor regulator (likely 5.0 V, ~500 mA) in a TBG package. To give precise cross-references, please share the datasheet or confirm: output voltage (5.0 V?), current limit, and regulator type. I can then provide direct equivalents from TI, Rohm, Maxim, etc. or guide a cross-reference search.
Pinout
Pin count: 8 pins (8-pin package, e.g., SO-8/MSOP-8).
Function: Buck (step-down) DC-DC converter with an integrated high-side switch. Provides a lower output voltage from a higher input, using external inductor and catch diode. Pin highlights typically include VIN, GND, EN (enable), FB (feedback), SW (switch node), BST/BOOT (bootstrap for gate drive), with the remaining pins usually NC (not connected) or no-connect.
