Str F6267 Datasheet Pdf Jun 2026

The is a hybrid integrated circuit (IC) designed specifically for flyback switching regulator applications . Manufactured by Sanken Electric Co., Ltd., this component is widely used in television power supplies, monitors, and various industrial switch-mode power supplies (SMPS). It combines a control circuit (incorporating an oscillator, error amplifier, and protection functions) with a high-voltage power MOSFET on a single chip. Technical Specifications Overview

: Slightly shifts the switching frequency dynamically to spread electromagnetic interference (EMI) energy across a broader spectrum, significantly reducing peak noise profiles.

: Requires a physical heatsink, adding to system cost and weight. 🛠️ Typical Applications Legacy CRT TVs and display monitors Early generation LCD TV power supplies Heavy-duty AC/DC power adapters VCR and DVD player power boards

: Uses cycle-by-cycle current limiting to protect against output overloads. Thermal Shutdown (TSD) str f6267 datasheet pdf
