Summary:
Because energy-efficient power supplies generate less heat, they can be used in harsh environments, such as white-light appliances that typically have higher ambient temperatures. Typical temperatures for such applications can be as high as 70C to 85C.
design feature
- Low cost, low component count, compact and lightweight, replaceable linear power supply design
- Extremely energy efficient
- High efficiency (>60% under full load)
- Low input power at no load (< 120 mW at 265 VAC AC input)
- High working temperature (70 °C)
- Integrated safety and reliability:
- Precise, auto-recovery and hysteretic shutdown with hysteresis to keep PCB temperature within safe conditions under all conditions
- High temperature shutdown (135 °C) function allows operation at high ambient temperatures
- Enters the auto-restart protection state when the output short circuit and the feedback loop open loop
- Meets CISPR-22/EN55022 B conducted EMI limits with EMI margin >10 dBmV
