Str F6267 Datasheet Pdf Online

A: The "H" variant typically has a lower RDS(on) and higher efficiency. Do not interchange without comparing the full datasheet.

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

Once the circuit begins oscillating, an auxiliary winding on the transformer delivers rectified DC voltage to take over powering Pin 4, ensuring higher running efficiency. str f6267 datasheet pdf

The UVLO circuit ensures that the IC does not attempt to switch the MOSFET until the VCCcap V sub cap C cap C end-sub

The built-in oscillator fixes the switching frequency of the regulator. Modulating the pulse width allows the IC to respond dynamically to load and input voltage changes, ensuring a stable DC output voltage on the secondary side of the power supply. Protection Topologies A: The "H" variant typically has a lower
