Description
- 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
- Maximum ratings specified may be applied, one at a time, without causing permanent damage to the product.
