The RT4503GQW is a highly efficient, 3-channel, linear, step-up constant current LED driver integrated circuit. It is designed for applications that require reliable and efficient operation over a wide range of voltage input and temperature operating conditions. The RT4503GQW is capable of providing constant current output over a wide range of input voltage and dimming control. This makes it ideal for use in outdoor lighting and other applications that require efficient and reliable LED drivers.
The RT4503GQW has an input voltage range of 2.7V to 18V with an output range of 8V to 20V. This range allows for indirect LED dimming control when operated with a suitable dimmer. The RT4503GQW also has thermal protection, short circuit protection, over-temperature protection, under-voltage protection and over-voltage protection to ensure reliable operation in a wide range of environments.
The RT4503GQW utilizes a novel architecture to provide three channels of constant current drive. Each channel has an adjustable current source and an external resistor to set the output current. The output current can be adjusted from the minimum level (Vf) to the maximum level (Vcs). This makes the RT4503GQW ideal for driving external LEDs with a wide range of nominal current.
The RT4503GQW also features a low standby current which allows the IC to remain in either shutdown or low current idle mode when the LED is not required. This makes the device ideal for applications where power efficiency and low current draw are paramount. In addition, the RT4503GQW has a wide operating temperature range of -40°C to +105°C making it suitable for use in harsh environmental conditions.
The RT4503GQW is a highly efficient and reliable PMIC - LED driver solution. Its wide input and output voltage range combined with its adjustable current source allows for indirect LED dimming control and improved system efficiency. Its low standby current and wide temperature range make it ideal for powering LEDs in harsh environments. The RT4503GQW is an ideal solution for a variety of LED driver applications.
