EC4304 - 1A High Brightness LED Driver

Datasheet Summary

Features

  • The EC4304 is a high-efficiency continuous mode inductive step-down converter which drives N-channel MOSFET and it is designed for driving single or multiple series connected LEDs from a voltage source higher than the LED voltage. It operates from input supply between 7V and 40V and provides and externally adjustable output current to 1A which is depending on supply voltage and external components. This EC4304 includes the output switch and high-side output current sensing circuit, which uses a.

1A, Hysteretic, High Brightness LED Driver with Internal Switch EC4304 GENERAL DESCRIPTION FEATURES The EC4304 is a high-efficiency continuous mode inductive step-down converter which drives N-channel MOSFET and it is designed for driving single or multiple series connected LEDs from a voltage source higher than the LED voltage. It operates from input supply between 7V and 40V and provides and externally adjustable output current to 1A which is depending on supply voltage and external components. This EC4304 includes the output switch and high-side output current sensing circuit, which uses an external resistor to set the output current. The ADJ pin will accept either a DC voltage or a PWM waveform.
