Product Highlights:

1. Lowest System Cost with Enhanced Flexibility:
   The TNY288DG offers several features that contribute to reducing system cost while providing flexibility in design. It utilizes 725V rated MOSFETs, allowing for increased BV derating margin. The line compensated overload power eliminates the need for additional components. With a significantly lower maximum overload change over the universal input voltage range, this chip offers optimal performance. The turn-on UV threshold can be sensed using a single external resistor, simplifying the sense line voltage control. The on/off control does not require loop compensation, further enhancing design simplicity. The current limit can be selected by the BP/M capacitor value, providing flexibility in current regulation. It maximizes the utilization of MOSFETs and magnetics while reducing system cost.

2. Enhanced Security and Reliability Features:
   The TNY288DG incorporates features that ensure security and reliability in operation. It offers accurate hysteretic thermal shutdown protection with auto-recovery, eliminating the need for manual reset. Auto-restart functionality provides less than 3% of the maximum power under short-circuit and open-loop fault conditions. The optional Zener diode output overvoltage shutdown adds an extra layer of protection. Fast AC reset with an optional UV external resistor improves system reliability. The low component count contributes to enhanced reliability and supports single-sided PCB layout. Its high bandwidth enables fast turn-on without overshoot and excellent transient load response. The extended creepage between DRAIN and other pins improves field reliability.

3. EcoSmart- Extremely Energy Efficient:
   The TNY288DG is designed to meet global energy efficiency regulations, making it an eco-friendly choice. It achieves low power consumption, with <30mW no-load power with bias winding and <150mW at 265VAC without bias winding. The ON/OFF control ensures constant efficiency even at very light loads, making it ideal for mandatory CEC regulations and EuP standby requirements.

Applications:

• PC standby and other accessories
• DVD/PVR and other low-power set-top decoders
• Appliances, industrial systems, metering, etc.
• Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.
