: Combines a high-voltage power sensing MOSFET alongside its specialized driver control circuit inside a robust TO-3P / ZIP-5 package style.
: Latches the circuit safely if internal bias lines exceed factory thresholds.
, the IC is attempting to start but shutting down. Check for secondary-side short circuits or a faulty optocoupler. If the voltage is
Shuts down the internal MOSFET on a cycle-by-cycle basis if the voltage across the S/OCP pin exceeds pre-defined limits due to secondary shorts.
Go to product viewer dialog for this item. is a high-performance designed by Sanken to simplify the design of power supplies. By integrating a high-voltage power MOSFET and a current-mode PWM controller into a single 5-pin SIP package, it reduces the physical footprint and complexity of AC/DC converters. ⚡ Technical Specifications Package : 5-pin SIP or TO-3P
For physical stock tracking, certified logistics sources like the Jotrin Electronics STR-F6267 Catalog or the Veswin Electronics Sanken Inventory provide updated component availability, regional packaging parameters, and architectural cross-references.
The updated document clarifies which faults cause vs latch-off . Overload (OLP) triggers auto-restart (1 second hiccup), while OVP on VCC triggers a full latch (requires AC power cycling).
Source / Overcurrent Protection. Connects to the switching source and senses current drops to prevent overload failures. VCC
