The SS6631STR is a PMIC - LED driver used for a wide range of applications, including automotive, industrial, and home lighting. It features low voltage, high current, and fast PWM (pulse width modulation) switching capability. The SS6631STR is an efficient, multi-output controller capable of driving up to four LEDs (Light Emitting Diodes) in series or in parallel. The SS6631STR has six operating modes which enable the user to choose the most suitable operating mode for their application.

Working Principles

The SS6631STR utilizes MOSFET (Metal Oxide Semiconductor Field Effect Transistor) technology along with PWM control to achieve the desired brightness and color. The MOSFET is a switch that is capable of rapidly switching between high-side and low-side voltages, allowing the LED to maintain constant brightness while switching between different current levels. The PWM control ensures that the LED current is consistent, allowing the user to maintain precise control of the LED brightness.

The SS6631STR also has a low ripple and noise feature which is important for applications with multiple LED sources. This feature enables the SS6631STR to maintain a consistent brightness level even in situations where the LED may be subjected to noise from external sources.
