CAT4238TD-GT3
High Efficiency 10 LED High Voltage Boost Converter, TSOT23, ON Semiconductor, RoHS


The CAT4238 is a DC/DC step-up converter that delivers an accurate constant current ideal for driving LEDs. Operation at a fixed switching frequency of 1 MHz allows the device to be used with small value external ceramic capacitors and inductor. LEDs connected in series are driven with a regulated current set by the external resistor R1. LED currents up to 40 mA can be supported over a wide range of input supply voltages up to 5.5 V, making the device ideal for battery-powered applications. The CAT4238 high-voltage output stage is perfect for driving mid-size and large panel displays containing up to ten white LEDs in series.

Features:

  • Drives High Voltage LED Strings (38 V)
  • Up to 87% Efficiency
  • Low Quiescent Ground Current 0.6 mA
  • Adjustable Output Current
  • 1 MHz Fixed Frequency Low Noise Operation
  • Soft Start “In-rush” Current Limiting
  • Shutdown Current Less than 1 uA
  • Automatic Shutdown at 1.9 V (UVLO)
  • Thermal Overload Protection
