PMIC - LED Drivers are a type of integrated circuit for controlling high-power light-emitting diodes (LEDs). A single PMIC – LED Driver can provide several functions such as current control, dimming control, fault detection, and on/off control. STP08CL596TTR is a high-performance low-cost LED Driver, which is widely used in consumer products and lighting projects.

The STP08CL596TTR has been designed to work with a wide range of LEDs and features an integrated charge pump circuit and optional pulse-width modulation (PWM) dimming support. With an integrated synchronous rectification, the STP08CL596TTR can provide up to 98% efficiency and up to 10W of output power.

The STP08CL596TTR features an external Voltage Control Buck (VCC) input for regulation, allowing for output current regulation via the VCC pin. The STP08CL596TTR also features an integrated Internal temperature protection circuit with auto-reset mode, Internal short protection and soft start circuit, and current overload protection. Its adjustable current setting up to 0.5A provides enhanced circuit protection and reduces power dissipation.

The STP08CL596TTR is ideal for a variety of LED lighting applications, including LED lighting fixtures, LED televisions, LED backlighting for monitors and displays, LED automotive lighting, LED street lighting, LED decorative lighting, LED signage, direct current (DC) power supplies, and general electric lighting.

The STP08CL596TTR features a controlled soft start mechanism and includes an adjustable current setting up to 0.5A, suitable for a variety of LED applications. It provides a wide output voltage range from 6V to 80V and can deliver up to 10W of output power.

The working principle of the STP08CL596TTR is that the integrated circuit converts DC power from a source into a controlled alternating current, or AC, with pulse width modulation of the voltage applied to the light emitting diode. The integrated circuit also controls the current, temperature and other features of the light emitting diode.

The power transistors responsible for the current output must be able to efficiently transfer power from the AC source to the light-emitting diode. This is achieved using an internal oscillator, which produces a frequency that is used to control the power switch, resulting in an AC output that is delivered to the LED.

The STP08CL596TTR can also be used for LED dimming and color changing applications, where the LED can be dimmed to reduce its intensity and adjust its color. The dimming control can be accomplished through either analog or PWM dimming signals, allowing for flexibility in the control system design.

The STP08CL596TTR also provides a wide range of protections to extend the life and reliability of the LED system. Its protection functions include an over temperature protection, open LED protection, current limit protection, over voltage protection, and brownout protection.

Overall, the STP08CL596TTR is an ideal LED driver for LED lighting applications that require high efficiency, stability, and reliability. It provides a wide input voltage range, a wide output voltage range, and up to 10W of output power. In addition, it features an integrated charge pump circuit and optional PWM dimming support, making it an ideal choice for commercial and industrial LED lighting applications.
