IR2D20U, PMIC – LED Drivers, plays an important role in intelligent control and power management. In recent years, with the rapid development of semiconductor technology, the IR2D20U products have been paid more and more attention. It provides up to 2A continuous output current control for white LED application, allows for PWM control for general purpose illumination applications, offers adjustable soft start features to reduce inrush current, and reduce application temperature.

The IR2D20U is a Three-channel LED driver made up of a linear regulator and three LED channels. It is designed to provide LED current over a wide range of LED forward voltage (number, typically 20V). It can be used for general illumination applications, such as LED displays, LED lighting, and automotive lighting.

The IR2D20U features three LED channels with 40KHz switching frequency, it supports a 0.5V to 20V range of LED forward voltages, and the low dropout voltage makes it the ideal choice for LED driver series or parallel applications. It has a high output precision, with a ±2% tolerance, and is capable of operating up to 2A LED current. It also has an integrated LED current ramp up and ramp down feature that can be controlled through a PWM signal, allowing lights to be dimmed gradually without producing a large inrush current.

The IR2D20U can also provide protection to the LED drivers during overcurrent, overvoltage, and over temperature conditions. Additionally, it features a built-in over temperature protection (OTP) circuit that can reduce product temperature when the temperature reaches a certain level. It also features short-circuit, low voltage, and over-current protection features to protect the LED drivers from static electricity, reversed connection, and other abnormal conditions.

In addition, IR2D20U has several features to support special applications. It has a 6-pin serial peripheral interface (SPI) for communicating with external microcontroller/DSP unit, allowing external adjustment and setting of current levels, setting dimming rate or flashing mode. It also has a temperature compensation circuit that can be used to compensate the output current due to changes in temperature.

The IR2D20U is an ideal choice for driving white LEDs in general illumination and automotive lighting systems, due to its wide input voltage range, wide output current range and high accuracy current regulation. It can easily be configured to operate in boost, flyback, or buck-boost topologies, depending on the number of LED strings and the LED forward voltage. It is suitable for non-dimmable LED applications and also supports constant current dimming mode for PWM dimming applications.

The IR2D20U is designed for use in applications that require high-efficiency, high-current and high-voltage operation. It is capable of regulating output currents from 0.5A to 2A with up to 6V input voltage. With its protection features, high accuracy and low dropout voltage, this product is the ideal choice for automotive and industrial LED applications.
