The STR-W6200D series are current-mode PWM ICs that incorporate controller chips.

These devices are manufactured using a proprietary high-voltage BCD process, and avalancheguaranteed MOSFETs.

Overcurrent protection (OCP) with ac input voltage compensation function; no additional peripheral circuits required.
minimizes dependency of OCP on ac input.
Overload protection (OLP) with integrated timer reduces power stress (temperature rise) at overload condition, requires no peripheral components.
Avalanche-guaranteed MOSFET improves device capability of withstanding excess surge voltage, providing a simple surge absorber circuit without breakdown voltage derating.
