The robust power delivery metrics of the STR-F6267 series made it an industry standard for mid-to-high wattage consumer electronic power modules. Its core use cases include: STR-F6267 Datasheet, PDF - ALLDATASHEET.COM
The STR-F6267 is a hybrid integrated circuit (IC) designed specifically for flyback switching mode power supplies (SMPS). It integrates a high-voltage power MOSFET and a controller chip into a single package. This device is widely used in consumer electronics like televisions, monitors, and power adapters due to its efficiency and robust built-in protection features. 1. Overview and Key Features Overvoltage Protection (OVP): Latches the circuit off if
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
Operating the device beyond these limits may cause permanent damage.
