RDK-83

RDK-83 switcher ICs cost effectively replace all unregulated isolated linear transformer based (50/60 Hz) power supplies up to 1.9 W output power. For worldwide operation, a single universal input design replaces multiple linear transformer based designs. The self-biased circuit achieves an extremely low no-load consumption of under 150 mW. The internal oscillator frequency is jittered to significantly reduce both quasi-peak and average EMI, minimizing filter cost.

• Lowest System Cost and Advanced Safety Features
  • Lowest component count switcher
  • Very tight parameter tolerances using proprietary IC trimming technology and transformer construction techniques enable Clampless™ designs - decreases component count/system cost and increases efficiency
  • Meets industry standard requirements for thermal overload protection - eliminates the thermal fuse used with linear transformers or additional components in RCC designs
  • Frequency jittering greatly reduces EMI - enables low cost input filter configuration
  • Meets HV creepage requirements between DRAIN and all other pins, both on the PCB and at the package
  • Proprietary E-Shield™ transformer eliminates Y-capacitor
• Superior Performance over Linear and Rcc
  • Hysteretic thermal shutdown protection - automatic recovery improves field reliability
  • Universal input range allows worldwide operation
  • Auto-restart reduces deli
