1. Describe
LinkSwitch-TN is specifically designed to replace all linear and A capacitor-fed (cap dropper) non-isolated power supply is 360 mA output current range at the same system cost, while Provides higher performance and energy efficiency. The LinkSwitch-TN device integrates a 700 V power MOSFET, Oscillator, Simple On/Off Control Scheme, High Voltage Switch Current source, frequency jitter, cycle-by-cycle current limit. and thermal shutdown circuitry to a monolithic IC. start up and operating power directly from the voltage DRAIN pin, no bias supply and associated circuits in a buck or flyback converter. fully integrated Auto-restart circuit in LNK304-306 safely limits output power Under fault conditions such as short circuit or open loop, Reduced component count and system-level load protection cost. The local power supply provided by the IC allows the use of non-safety rated optocouplers as level shifters for further Enhanced Buck and Load Regulation buck-boost converter, if required.
2. Product Highlights
1. Cost-effective alternative to linear/capacitive dropper
- Lowest cost and component count buck converter solution
- Fully integrated short-circuit and open-loop fault protection with auto-restart - Saves external component costs
- LNK302 adopts a simplified controller, no automatic restart is required, and the system cost is extremely low
- 66 kHz operation with precise current limit - Allows up to 120 mA output current using low cost off-the-shelf 1 mH inductor
- Tight tolerances and negligible temperature variations
- High breakdown voltage of 700 V provides excellent input surge immunity
- Frequency jitter significantly reduces EMI (~10 dB)
- Minimize EMI filter cost
- High thermal shutdown temperature (min +135 °C)
2. Higher performance than discrete buck and passive solutions
- Supports buck, buck-boost and flyback topologies
- System level thermal overload, output shorts and opens Control loop protection
- Excellent line and load regulation even in typical configurations
- High bandwidth provides fast turn-on without overshoot
- Current limit operation rejects line ripple
- Universal input voltage range (85 VAC to 265 VAC)
- Built-in current limit and hysteretic thermal protection
- more efficient than passive solutions
- Higher power factor than capacitor powered solutions
- Fully manufacturable in SMD
3. EcoSmart™ – Extremely energy efficient
- Typically consumes only 50/80 mW in a self-powered buck 115/230 VAC input no-load topology (optical feedback)
- Typically consumes only 7/12 mW in flyback topology External bias at 115/230 VAC input, no load
- Compliant with California Energy Commission (CEC), ENERGY STAR and EU requirements
3. Application
1. Appliances and timers
2. LED drivers and industrial controls
4. Pin function description
1. Drain (D) Pin: Power MOSFET drain connection. Provides internal operations start-up and steady-state operation current.
2. Bypass (BP) Pin: Connection point for a 0.1 mF external bypass capacitor Internally generated 5.8 V supply.
3. Feedback (FB) Pin: The switching of the power MOSFET is Controlled by pins. MOSFET switching is terminated when Currents greater than 49 µA are delivered to this pin.
4. Source (S) pin: This pin is the power MOSFET source connection. it is also Ground reference for bypass and feedback pins.
5. Pin configuration
