This IC is widely regarded as a "workhorse" component for mid-range power applications.
Senses the voltage drop across an external resistor connected to the Source pin. If the current exceeds the threshold, the duty cycle is immediately truncated on a pulse-by-pulse basis. Overvoltage Protection (OVP): If VCCcap V sub cap C cap C end-sub
This IC stands out because it integrates a high-voltage and a current-mode PWM controller into a single, compact package. This integration not only reduces the number of external components required but also streamlines the design process, leading to more reliable and efficient power supplies. str f6267 datasheet pdf

The STR-F6267 is famously a key component in the power supply units (PSUs) of many Sony Trinitron CRT televisions, such as the KV-21FB140, KV-21FS140, KV-SW21M80, and the KV-BZ21 chassis series. In these devices, the IC serves as the primary SMPS controller, regulating the main B+ voltage and auxiliary supplies.
A standard STR-F6267 power supply includes: Overvoltage Protection (OVP): If VCCcap V sub cap
This component is primarily found in . It functions as a high-voltage power switch and controller, integrating a power MOSFET and a control IC into a single package.
