SI52208-A01AGMR

The SI52208-A01AGMR is a Clock/Timing - Application Specific product, specifically designed for Power-over-Ethernet (PoE) applications. It is a multi-output synchronous buck regulator with a high-efficiency LED driver that supports a wide range of LED lighting fixtures. The power product has two main features: a high-IQ buck controller and a multi-output LED driver.

The SI52208-A01AGMR is an integrated device that includes several components that provide circuit protection, fault monitoring and thermal management. The buck controller operates on a maximum of 18V input voltage, and is capable of delivering up to 25A continuous current. The buck controller has a soft-start feature to ensure a reliable start-up of the PoE applications and to avoid inrush currents. The built-in fault-tolerant features protect the device against excessive power losses and over-voltage conditions. The device also supports Brownout protection to protect from low input voltages.

The multi-output LED driver includes integrated high-brightness LED drivers, dimming control, and color-correction. The driver can be used to control up to four independent strings of LEDs. The output voltage of each string can be adjusted between 0-15V, allowing for maximum flexibility in applications. The LED driver also supports dimming control with pulse-width modulation, allowing for dynamic control of LED brightness. The LED driver is also equipped with a color-correction feature to provide superior color accuracy while working with a wide range of lighting fixtures.

The SI52208-A01AGMR also features advanced thermal management features including an on-board temperature sensor and a digital thermal shut-down. The on-board temperature sensor can detect the device temperature and shut down the device in extreme cases, thus protecting the components from overheating. The device also supports overvoltage protection and overcurrent protection for maximum protection against short circuits and overloading.

The SI52208-A01AGMR is an integrated solution that helps PoE applications reduce power losses, improve efficiency, and decrease overall costs. The integrated buck controller and LED driver make the SI52208-A01AGMR the perfect choice for applications requiring high power and energy efficiency. The integrated protection and thermal management features of the device ensure superior performance and reliability in challenging applications.
