PMIC - LED Drivers

LED5000PHR is a popular and widely used LED driver designed specifically to meet the power output and voltage modulation requirements of LEDs. It is typically used in a variety of general lighting applications like display walls, task lighting or automotive rear-parking lamps. This device features a wide input voltage range and is especially well-suited for use with mains, battery or automotive power supplies. The LED5000PHR also offers a unique power-supply architecture that provides reliable operation at low LED currents.The LED5000PHR LED driver is a current-mode, pulse width modulation (PWM) LED driver that uses a resonant, voltage-mode topology. This topology is optimized for the efficient utilization of current independent of LED load or environmental conditions. With this architecture, the output voltage is regulated by sensing the voltage along a resistive element in relation to the reference voltage. When the feedback voltage is equal to the reference, the output stops running. This method of monitoring allows the output voltage to remain constant regardless of the changes in LED current and ambient temperature.The LED5000PHR LED driver is designed to meet the LED industry\'s highest performance requirements. It incorporates sophisticated power-foldback power limiting technique, I2C interface communication, over temperature protection, and a wide range of modulation frequencies. The LED5000PHR is capable of operating both in open and closed-loop modes, allowing it to regulate multiple LED strings for various applications.The LED5000PHR integrates several features that make it unique in the LED lighting industry. First, its frequency operation is tailored to provide optimal power efficiency when used with a step-down type of AC/DC converter. This allows the converter to maintain a constant frequency of operation regardless of the load conditions.The second most important feature is its robust power management features. For example, the device includes input voltage protection, short-circuit protection, over-temperature protection, and an integrated low-battery detection circuit. The combination of these features provides complete protection against potential accidental misuse of the device.In addition, the LED5000PHR LED driver integrates a sophisticated auto-dimming feature. This feature is designed to manage the brightness of the LEDs as a function of the ambient light reducing the power consumption and enabling low light levels when necessary.The LED5000PHR LED driver\'s output current is adjustable from 0 to 1800 mA providing a range of LED power levels. Additionally, its output voltage is capable of modulation from 0 to0.65V in 2mV increments. With this adjustable output current and voltage, the LED5000PHR can drive a variety of different LEDs in different applications.In conclusion, the LED5000PHR LED driver is a highly versatile and efficient device designed to meet the needs of the LED lighting industry. With its adjustable output current, voltage and operating frequencies, this device can be used in a wide range of applications. The integrated power management features enhance the safety of the output stages while providing a reliable and consistent operation of the device. Overall, the LED5000PHR is a very useful and versatile device that provides superior performance in a variety of applications.
