EC4304
1A, Hysteretic, High Brightness LED Driver with Internal Switch
GENERAL DESCRIPTION
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. This will provide either a continuous or gated output current depending upon the control frequency. The PWM filter components contains a soft-start rising time setting. The soft-start time can be increased by using an external capacitor from the ADJ pin to ground. Applying a 0.2V or lower to the ADJ pin turns the output off and switches the device into a low current standby state.
FEATURES
EC4304
具有內部開關的 1A、遲滯、高亮度 LED 驅動器
一般說明
EC4304 是一款驅動 N 溝道 MOSFET 的高效連續模式電感降壓轉換器，專為從高於 LED 電壓的電壓源驅動單個或多個串聯 LED 而設計。 它採用 7V 至 40V 的輸入電源供電，並提供高達 1A 的外部可調輸出電流，具體取決於電源電壓和外部組件。
EC4304 包括輸出開關和高側輸出電流檢測電路，它使用外部電阻來設置輸出電流。
ADJ 引腳將接受直流電壓或 PWM 波形。 這將根據控制頻率提供連續或門控輸出電流。 PWM 濾波器組件包含軟啟動上升時間設置。 可以通過在 ADJ 引腳和地之間使用一個外部電容器來增加軟啟動時間。 向 ADJ 引腳施加 0.2V 或更低電壓可關閉輸出並將器件切換到低電流待機狀態。
