Details

TopologieGegentaktflusswandler
Schaltfrequenz160-420 kHz

Beschreibung

Confidential c2000 ref design

Eigenschaften

  • Push-pull driver for transformers
  • Wide input voltage range: 2.25 V to 5.5 V
  • High output drive: 1 A at 5 V supply
  • Low RON 0.25 Ω max at 4.5 V supply
  • Ultra-low EMI - Spread spectrum clocking
  • Precision internal oscillator options: 160 kHz (SN6505A) and 420 kHz (SN6505B)
  • Synchronization of multiple devices with external clock input
  • Slew-rate control
  • 1.7 A Current-limit
  • Low shutdown current: <1 μA - Thermal shutdown
  • Wide temperature range: –55°C to 125°C
  • Small 6-Pin SOT23 (DBV) package
  • Soft-start to reduce In-rush current
