The STR-F6267 is an offline switching regulator IC, primarily designed for use in the primary section of Switching Mode Power Supplies (SMPS). Its main function is to convert high-voltage AC mains power into stable, regulated DC power for electronic devices.
The STR-F6267 is a product of , a well-regarded Japanese manufacturer of power management semiconductors, including the popular "STR" (Switching Type Regulator) series. When searching for the correct documentation, this is the manufacturer name to use.
Always check the exact part number and manufacturer when dealing with high-voltage SMPS circuits to ensure compatibility.
Often found in similar topologies, though physical package styles and internal timing characteristics must be cross-checked with their respective datasheets. str f6267 datasheet pdf upd
A global electronics distributor, Jotrin provides a comprehensive product page with the option to download the datasheet in PDF format. The "Product Details" section confirms the IC's role as an offline switching regulator.
The AC mains voltage is rectified and filtered to produce a high-voltage DC bus (~300V DC). This bus connects to the primary winding of the switching transformer and to pin 5 (DRAIN) of the IC. An auxiliary winding on the transformer provides a lower voltage to charge a capacitor, which then powers the IC's once the circuit is running.
The STR-F6267 is a (Single In-line Package) power IC designed primarily for Switched-Mode Power Supplies (SMPS) . It is widely used in power supply circuits that require high efficiency, low EMI (Electromagnetic Interference) noise, and low manufacturing costs.
The power supply pin for the internal control circuitry. The STR-F6267 is a product of , a
To ensure accuracy and relevance, datasheets are regularly updated and revised. The STR F6267 datasheet PDF update history is as follows:
voltage exceeds safe operating limits (typically around 22V–25V).
The typical application of the STR-F6267 can be seen in the chopper circuit of a Samsung D61B DLP TV. In this design, the IC (labeled IC8301) is the heart of the primary switching section. The oscillation of the IC generates a voltage in the secondary coil of the transformer, which is then regulated by a separate chopper IC (SI-8050S) on the secondary side to provide stable voltages.
