The TNY278PN is a TinySwitch-III energy-efficient, off-line Switcher with enhanced flexibility and extended power range, incorporates a 700V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability.

• Simple ON/OFF Control, No Loop Compensation Needed
• Selectable Current Limit Through BP/M Capacitor Value
• Higher Current Limit Extends Peak Power or, in Open Frame Applications, Maximum Continuous Power
• Lower-current Limit Improves Efficiency In Enclosed Adapters/Chargers
• Allows Optimum TinySwitch-III Choice by Swapping Devices with No Other Circuit Redesign
• Tight I²f Parameter Tolerance Reduces System Cost
• Maximizes MOSFET and Magnetic Power Delivery
• Minimizes Max Overload Power, Reducing Cost of Transformer, Primary Clamp and Secondary Components
• ON-time Extension, Extends Low Line Regulation Range/Hold-up Time to Reduce Input Bulk Capacitance
• Self-biased - No Bias Winding or Bias Components
• Frequency Jittering Reduces EMI Filter Costs
• Pin-out Simplifies Heatsinking to PCB
• SOURCE Pins are Electrically Quiet for Low EMI
• Enhanced Safety and Reliability
• Accurate hysteretic thermal shutdown protection with automatic recovery
• Improved Auto-restart Delivers <3% of Maximum Power in Short-circuit and Open Loop Fault Conditions
• Output Overvoltage Shutdown with Optional Zener
• Line Undervoltage Detect Threshold Set Using a Single Optional Resistor
• Very Low Component Count Enhances Reliability and Enables Single-sided Printed Circuit Board Layout
• High Bandwidth Provides Fast Turn On with No Overshoot and Excellent Transient Load Response
