概述

Description

RT6214AHRGJ6F is a RichTek synchronous buck DC-DC converter IC. It integrates the high- and low-side MOSFETs and a current‑mode PWM controller to step down a higher input voltage to a regulated lower voltage for system rails in portable/embedded devices. Key features typically include adjustable output via external feedback, programmable switching frequency, enable/soft-start, and protections such as overcurrent, over‑temperature, and undervoltage lockout. It is offered in a compact package (variant and package code indicated by “RGJ6F”) and is designed for use with ceramic output capacitors and an external inductor per reference designs. The exact electrical specs (input/output voltage ranges, max current, fsw, and recommended external components) depend on the specific variant; consult the RT6214A datasheet and packaging notes for precise values.

Package

QFN-16 (WDFN-16) package, 3x3 mm, with wettable flanks.

Pinout

- Pin count: 16 pins (QFN package)
- Function: Single-channel, high-efficiency synchronous buck (step-down) DC-DC regulator with integrated MOSFETs; converts input voltage to a regulated output. Includes typical pins such as VIN, GND, SW/LX (switch node), BST (bootstrap), FB, EN, PG, and other control/NC pins.

Manufacturer

Manufacturer: Richtek Technology Corp. (Richtek).
What kind of company: A Taiwanese fabless semiconductor company that designs and markets analog and power-management ICs, including DC-DC regulators and PMICs for consumer electronics.

Application

RT6214AHRGJ6F is a RichTek power-management IC. Typical applications include Li‑ion battery charging and protection, efficient DC‑DC regulation for system rails, USB charging and power-path management, and general PMIC tasks in portable electronics.
