By incorporating high-efficiency Power MOSFET elements rather than traditional bipolar transistors, it supports a higher oscillator frequency (up to 100kHz), which drastically reduces the physical footprint requirements for external pulse transformers and filter capacitors.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features \u0026amp; Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Self-Excitation Type Feedback Control Off-Line Switching Regulator\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Output Power:\u003c\/strong\u003e 180W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Topography:\u003c\/strong\u003e Combines power switching, driver circuits, error amplifiers, and overcurrent protection (OCP) circuits on a single sub-module\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Constraints:\u003c\/strong\u003e 500V Maximum Drain-Source Breakdown Voltage ($V_{(BR)DSS}$)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Type:\u003c\/strong\u003e 11-Pin Single In-Line Package (SIP) featuring Sanyo's signature metal substrate backing plate for direct heatsink installation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications:\u003c\/strong\u003e Primary power supply regulator module for legacy CRT\/CTV analog color televisions and older office automation hardware\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Sanyo Electric Co., Ltd.
