SSL21081T is a high voltage Integrated Circuit (IC), intended to drive LED lamps from the mains supply in general lighting applications

Features and benefits

  • High-efficiency switch mode buck driver
  • Integrated 300 V power switch
  • Power-efficient boundary conduction mode of operation
  • - Zero Current Switching (ZCS) for turn-on of switch
  • - Zero voltage or valley switching for turn-on of switch
  • Direct PWM dimming possible
  • Fast transient response through cycle-by-cycle current control:
  • - Negligible AC mains ripple at LED current and minimal total capacitor value
  • - No over or undershoots in the LED current
  • Full range of Internal Protections
  • Low component count LED Driver solution
  • Compatible with wall switches with built-in indication light during standby

Applications

  • High voltage LCD backlighting for LCD monitors and televisions
  • Retrofit LED lamps in general lighting applications

NXP Semiconductors' products are specifically designed and manufactured to be used within the electrical, thermal, mechanical and other parameters set forth in NXP Semiconductors' data sheets. Quality and reliability data provided by NXP Semiconductors, such as MTBF, MSL and FIT, is intended to be a non-binding estimate of product performance based upon diffusion process, history only. It does not imply that any performance levels reflected in such data can be met if the product is operated outside the conditions expressly stated in the latest published data sheet for a device or in your application.

The RoHS data provided hereunder is preliminary and non binding for NXP Semiconductors. NXP Semiconductors does not accept any liability related to this data.

NXP Semiconductors products are not designed, authorized or warranted to be suitable for use in medical, military, aircraft, space or life support equipment, nor in applications where failure or malfunction of an NXP Semiconductors product can reasonably be expected to result in personal injury, death or severe property or environmental damage nor for any other use that is not explicitly agreed between the parties.

Any use of NXP Semiconductors' products beyond the scope defined in the current NXP Semiconductors' data sheet voids all warranty responsibility of NXP Semiconductors with respect to such devices, and also voids all responsibility of NXP Semiconductors with respect to any applications assistance, product design, software performance or services of any kind that were or may have been performed in connection with the sale of any such devices.

Further, resale of NXP Semiconductors' products or services with statements different from or beyond the parameters stated by NXP Semiconductors for that product in official NXP Semiconductors data sheets, or without the warnings or instructions provided by NXP Semiconductors, voids all express and any implied warranties for the associated NXP Semiconductors product or service, and is an unfair and deceptive business practice.
