概述
Description
RT9169-33GVL is a fixed-output buck regulator from RichTek (RT9169 family). It integrates the switching MOSFETs and control logic to convert a low input voltage into a stable 3.3V output for digital rails. Typical features include enable control, soft-start, overcurrent/overtemperature protections, and a fixed switching frequency with high efficiency in a compact RoHS-lead-free package. The “-33” indicates 3.3V output; “GVL” denotes the specific package/variant. It’s suitable for mobile/compact devices and PMIC rails. For exact specs (input range, max output current, efficiency, pinout, and application circuit), consult the official RT9169-33GVL datasheet from RichTek.
