The STR-F6267 series is widely recognized for its robust performance in consumer electronics, including television power supplies, monitors, and industrial equipment requiring regulated off-line switching power.
To get the most accurate and up-to-date information, it is essential to consult the official datasheet. The datasheet provides comprehensive technical specifications, including:
The STR-F6267 integrates a power MOSFET and a current-mode PWM controller into a single 5-pin SIP (Single In-line Package) or TO-3P package. Its primary goal is to simplify power supply design by reducing the number of external components needed on a PCB. As a crucial component in many modern devices,
A detailed analysis of a Samsung D61B service manual offers in-depth insight into how the STR-F6267 implements protection mechanisms. The VCC terminal powers the oscillator. An over-voltage latch activates when the VCC exceeds 28V(TYP). The Over-Current Protection (OCP) is pulse-by-pulse: the IC detects the drain current peak value each cycle via detection resistors R8301 and RX8301 (connected to Pin 4). When the threshold is exceeded, the FET cuts off immediately until the next cycle, effectively limiting the output power. Additionally, the IC performs UVLO (Under Voltage Lockout) during severe overloads on the secondary side, preventing damage.
