ADD5207XCPZ-RL

ADD5207XCPZ-RL is a dual inductor buck-boost LED driver controller with enable input and output regulation feature. This advanced device is designed to ride through input sag and surge, output over-voltage, over current and over temperature while keeping the output voltage regulated. This IC is suitable for driving LEDs in both constant voltage and constant current mode. It is an ideal solution for driving up to 2 independent channels of LEDs, providing an adjustable output current of up to 1.25A per channel.

ADD5207XCPZ-RL operates in a buck-boost configuration and utilizes two independent inductors and one transistor to drive up to 2 LEDs. It features a precision voltage regulator, with voltage accuracy of ±5% at no load, that steps up or down the input voltage accordingly to maintain the desired LED string voltage. The LED current is regulate accurately with a peak current accuracy of ±3%. It can also be set to regulate the total peak current, giving more flexibility when driving more strings in parallel.

ADD5207XCPZ-RL features a wide voltage input range of 7V to 100V, making it suitable for a large range of applications such as street lights, decorative lighting, automotive applications, and illumination. It offers excellent low-light mode efficiency as it supports higher switching frequency up to 1MHz. It offers a DIMBUS interface for dimmer control, and an enable input that can be used to shut off the power supply when required.

ADD5207XCPZ-RL includes a Digitally Programmable Logic for digitally controlling the regulator parameters, such as the maximum current, output voltage, allowing closed loop control of the output voltage in constant voltage mode and constant current mode. The chip can also be configured to offer a dynamic response to the light stimuli and react accordingly to the changes in light intensity. It is also equipped with an open LED-detection functionality and an output-short-circuit protection mode.

ADD5207XCPZ-RL also features an Overload Protection (OLP) circuit to protect the IC and LEDs from over-voltage, over-current and thermal runaway conditions. The OLP is based on the sensing of the inductor current and its timing characteristics. This device provides the highest level of safety and performance in LED drivers.

Overall, ADD5207XCPZ-RL is an ideal LED driver solution for a wide range of applications. Its wide input range, accurate voltage and current regulation, and its range of safety features make it suitable for constant voltage and constant current LED lighting. This device also offers a range of convenience features that make it very user friendly.
