TinySwitch-III incorporates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design fl exible solution with a low system cost and extended power capability

FEATURES:

  • Simple ON/OFF control, no loop compensation needed
  • ON-time extension – extends low line regulation range/hold-up time to reduce input bulk capacitance
  • Frequency jittering reduces EMI filter costs
  • Pin-out simplifies heat sinking to the PCB
  • SOURCE pins are electrically quiet for low EMI

SPECIFICATIONS:

  • Drain Voltage: -0.3 to 700V
  • Drain Peak Current: 1200mA
  • ENABLE Voltage: -0.3 to 9V
  • ENABLE Current: 100mA
  • ON State Resistance (max): 4.5Ω
  • Package: DIP-8B

APPLICATION:

Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc. PC Standby and other auxiliary supplies DVD/PVR and other low power set top decoders Supplies for appliances, industrial systems, metering, etc.
