概述

Description

NCP803SN160T1G is ON Semiconductor’s fixed-output buck (step-down) switching regulator in a small package. It belongs to the NCP803 family and provides a fixed 1.6 V output (core rail) from a higher input voltage, with the power MOSFET and control circuitry integrated for compact, efficient power conversion.
Key points:
- Fixed-output buck regulator with integrated switch
- Fixed 1.6 V output variant (NCP803SN160)
- Protections: undervoltage lockout, overcurrent/short-circuit protection, thermal shutdown
- Designed for low-component-count, compact power rails in portable electronics and SoC cores
- Typical package: small SOT-23/SOT-23-like form factor (T1G), with reel options available
For exact electrical specs (VIN range, switching frequency, enable/soft-start behavior, thermal limits, pinout), consult the official datasheet for NCP803SN160T1G.

Package

SC-70-3 (3-pin) package.

Pinout

- Pin count: 16 pins (16‑pin package, e.g., QFN/TSSOP style as per SN160 packaging).
- Function: NCP803SN160T1G is a 16‑pin buck switching regulator (DC‑DC converter) with an integrated controller and high‑side switch. It requires external inductor, diode/rectifier (or synchronous rectifier), and feedback components to regulate the output. Includes pins for enable/soft-start, feedback, bootstrap, input/output grounds, and protection features.

Manufacturer

- Manufacturer: ON Semiconductor (branded onsemi).
- What kind of company: An American multinational semiconductor company that designs, manufactures, and sells energy-efficient power management, analog, sensor, and other integrated circuit products.

Application

Applications for NCP803SN160T1G include:
- Battery-powered, space-constrained portable devices (wearables, handheld gadgets, cameras)
- IoT sensors and microcontroller-based systems
- USB-powered peripherals and compact consumer electronics
- Embedded systems requiring a stable low-voltage regulator
- Other small-form-factor applications needing low quiescent current regulation
