MP6001 Monolithic Flyback/Forward DC-DC Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MP6001 is a monolithic Flyback/Forward Integrated 0.9 150V Power Switch DC-DC converter which includes a 150V power Cycle-by-Cycle Current Limiting switch and is capable of delivering up to 15W Programmable Switching Frequency output power. It can also be used for boost and Duty Cycle Limiting with Line Feed Forward SEPIC applications. Integrated 100V Startup Circuit Internal Slope Compensation The MP6001 uses the fixed-frequency peak Disable Function current mode primary controller architecture. It has an internal soft-start, auto-retry, and Built-in Soft-Start incorporates over current, short circuit, and Line Under Voltage Lockout over-voltage protection. The MP6001 can also Line Over Voltage Protection skip cycles to maintain zero load regulation. Auto-Restart for Opened/Shorted Output Zero Load Regulation It has a direct optocoupler interface which Thermal Shutdown bypasses the internal error amplifier when an isolated output is desired. APPLICATIONS The MP6001 is ideal for telecom applications, Telecom Equipment and is available in a compact, thermally VoIP Phones, Power over Ethernet (PoE) enhanced SOIC8 package with an exposed pad.
