Semtech SC104

Micro-Power Constant-Current DC/DC Converter

The SC104 is a micro power dc-dc step-up converter which converts an input voltage, in the range of 1.55V to 10V, to a constant current. The part features a range of user programmable voltages and currents including dynamic adjustment of the “constant” current.

Features


  • Adjustable output current using pulse-width modulation or analog voltage input
  • 38 V output capability supports up to 10 white LEDs
  • Wide range of input voltages: 1.55 V to 10 V
  • Low quiescent current
  • 0.5 µA standby current in shutdown
  • Programmable cycle-by-cycle current limit
  • Surface mount packaging (3 x 3 mm 8-pin MLP)
  • Output voltage and over-temperature protection

Applications


  • White LED supplies
  • Color LED supplies
  • Cellular phones
  • PDAs
  • Electronic books
  • Handheld computers
  • Wireless web appliances
