PMIC - LED Drivers are a sub-category of power management integrated circuits, which are used to convert the current source to operate LED arrays. Among them, STAP08DP5XTTR is an 8-channel, high-efficiency, current source/sink driver with adjustable output current. It is widely used in backlight applications in the field of LCD.

STAP08DP5XTTR application field and working principle is based on the following six factors:

• Efficiency: The STAP08DP5XTTR has a power efficiency of up to 94.1%. This efficiency is achieved due to its true-current source/sink architecture, which eliminates RISET and FET current variation. Furthermore, its integrated power switches and current output settings can be easily adjusted to meet the needs of each application.
• Input Power Security: STAP08DP5XTTR is equipped with a programmable Voltage Limiter (VLO). This feature limits the power input of the device and provides extra protection of the electric source, ensuring that no overloading or excessive current can damage the appliance.
• Unique Current Source/Sink: STAP08DP5XTTR enables current control of up to 8 channels individually. It combines the current source mode and current sink mode of LED driving. This allows the LED driver to control LED brightness with both direct and inverse pulse width modulation.
• LED Short Circuit Protection: STAP08DP5XTTR offers comprehensive circuit protection of LED by using a smart current limit feature. The circuit limits the amount of current flowing out from the driver output port, thus protecting the LED from over-current damage.
• Flexible Adjustment Modes: STAP08DP5XTTR provides the configurable brightness control by direct and pulse width modulation with over 8-bit dimming resolution. It also supports adjustable current offset (ADC) setting and temperature compensation (OTA). Besides, high starting voltage and configuration of current phase delay is also available.
• Low Power Dissipation: STAP08DP5XTTR runs at up to 8.5V, which is lower than most applications, requiring only 2.5mW of power dissipation. This in turn reduces the risk of processor and system crash, facilitating extended service life for the device.

In summary, the STAP08DP5XTTR is a highly efficient LED driver for a wide range of applications, including backlighting for LCDs. With its adjustable current sink/source, programmable voltage limiter, LED short circuit protection, flexible adjustment modes, and low power dissipation, it is versatile and reliable. The device also supports a high conversion efficiency, which can save power resources and reduce the cost of energy consumption. Therefore, it is definitely an optimal choice for power management
