ILD4071XUMA1

The ILD4071 is a highly integrated smart LED buck controller with built in protection functions.

• Constant Current Generation
• Wide Input Voltage Range from 5V to 40V
• Peak Current Regulation
• Very low current consumption (<2uA) in Sleep Mode
• Integrated power transistor with low saturation voltage
• Integrated fast freewheeling diode
• Integrated load current sense resistor
• Integrated status pull down transistor
• Overtemperature Protection
• Switching frequency (typ. 200kHz) adjustable via external RC network
• External PWM Dimming Input
• Integrated PWM Dimming Engine
• Analog Dimming (output current adjustable via external low power resistor and possibility to connect PTC resistor for LED protection during overtemperature conditions)
• Stable switching frequency due to fix OFF-time concept with VREC (supply voltage)feedforward
• Under- and Overvoltage shutdown with hysteresis
• Small thermally enhanced exposed heatslug SMD package
• Green Product (RoHS) Compliant
