NCP81071BMNTXG

NCP81071BMNTXG is ON Semiconductor’s synchronous buck DC-DC converter in a small BMNTXG package. It’s designed to generate a stable, low-voltage rail from a higher input for battery-powered and portable applications, with minimal external parts.
Key points:
- Synchronous buck regulator with integrated high- and low-side MOSFETs
- External resistor set for adjustable output
- Fixed switching frequency with PWM/PFM modes for good efficiency across load
- Protections: overcurrent, thermal shutdown, and enable control
- Soft-start and power-good signaling
- RoHS-compliant, compact package suitable for space-constrained designs
Typical uses:
- Smartphones, tablets, wearables, IoT devices, and other portable electronics
For exact electrical specs (input range, output voltage range, current capability, efficiency, pinout), consult the NCP81071BMNTXG datasheet and related application notes.
