CAT37 Datasheet CMOS White Led Driver

Manufacturer: onsemi

Overview: CAT37 CMOS White LED Driver Boost Converter.

General Description

The CAT37 is a DC/DC step up converter that delivers a regulated output current.

Operation at a constant switching frequency of 1.2 MHz allows the device to be used with very small value external inductor and ceramic capacitors.

The CAT37 is targeted to drive multiple white light−emitting diodes (LEDs) connected in series and provides the necessary regulated current to control the brightness and the color purity.

Key Features

  • Low Quiescent Ground Current (0.5 mA Typical).
  • Power Efficiency Over 80%.
  • Compatible Pinout with LT1937.
  • Adjustable Output Current (up to 40 mA).
  • High Frequency 1.2 MHz Operation.
  • Input Voltage Operation down to 2.5 V.
  • Low Resistance (0.5 W) Power Switch.
  • Drives up to 4 White LEDs in Series.
  • Shutdown Current Less than 1 mA.
  • Load Fault Protection Against Open.
  • circuits.
  • Low Value External Co.
