LC5222S

The LC5222S is a PMIC - LED Drivers designed to drive four parallel strings of LEDs. The device is optimized for OLED and printed circuit board (PCB) displays and provides an integrated range of drive current and brightness levels. It provides 12V of input voltage and utilizes a Serial Peripheral Interface (SPI) to control and monitor the device. With a maximum output current of up to 200mA, it is ideal for applications that require high power efficiency and flexibility.

The device has a programmable step-up regulator for LED current and brightness control. The step-up regulator can be easily configured with internal DIP switches. The device also has an on-board linear regulator with thermal protection to offer additional protections. The integrated thermistor provides additional protection against sudden changes in LED current.

The LC5222S offers a wide range of adjustable current and brightness levels. It supports up to 400mA of continuous output current and up to 450mA of peak output current for both single and multiple LEDs. The integrated programmable output voltage ranges from 0.72V to 5.25V and can support up to 8 strings of LEDs. In addition, the device offers independent dimming and color control of multiple channels.

The device also features a low turn-on voltage, low standby current and low output voltage ripple. This allows it to run cooler and more efficiently while maximizing display performance. It also provides protection against over-current, over-voltage, and short circuit protection.

The LC5222S is simple to use and highly configurable. It is built upon proprietary design and offers an advanced interface and control architecture. The device features an open-loop architecture, which makes it easy to implement in a wide range of applications. The on-board SPI interface allows the user to control and monitor the device. The user can use a dedicated programming language for easy programming.

The LC5222S can be used in a variety of applications, such as LCD, OLED and LED displays, flash lighting, and automotive lighting. It supports many standard LED configuration options, such as single and parallel LED strings, and provides integrators with a robust and reliable solution for cost-effective and high performance LED lighting systems.
