CL325SG-G Application Field and Working Principle

CL325SG-G is a power management integrated circuit (PMIC) that belongs to the category of LED drivers. As a type of PMIC, the CL325SG-G integrates power conversion and control functions in a single chip, providing a more effective and efficient way to drive and monitor the current of light emitting diodes, or LEDs, for various applications.

The CL325SG-G has several key features: its wide input voltage range, its protection and control functions, its range of output current selection, its programmability, and its compatibility with TTL logic.

Application Field

The CL325SG-G drivers are commonly used in general lighting applications such as lamps, strips, spotlights and bulbs, as well as backlight, LCD and display applications. They are suitable for driving all kinds of LED modules and LED panels, including those designed for power-saving, cooling and brightness compensations.

Protection and Control Functions

The CL325SG-G offers protection and control functions that guarantee the safety of the LED module during its operation. These include current limiting, thermal protection, and over-voltage protection. In addition, the CL325SG-G also includes a pulse-width modulation (PWM) dimming function, which enhances the energy efficiency of the LED module and allows for a wide range of brightness adjustment.

Wide Input Voltage Range

The CL325SG-G LED drivers are designed to work with a wide range of input voltages, between 6V and 35V. This wide range of input voltage allows the drivers to be used in an array of lighting applications, including converters with input voltages of 12V and 24V, making the drivers suitable for use in commercial buildings and homes.

Range of Output Current Selection

The CL325SG-G drivers also feature a range of output current selection, which improves system power savings and reliability. With a wide range of output current selections, the system designer can tailor the driver to meet the requirements of different LED modules and light sources for different applications.

Programmability

The CL325SG-G features a programmable dimming function, which allows for customized brightness control to meet the usage requirements of a wide range of applications. Additionally, the CL325SG-G offers the flexibility of using a variety of dimming methods, such as pulse-width modulation (PWM), analog, or digital dimming.

Compatibility with TTL Logic

The CL325SG-G is compatible with TTL logic, meaning it can receive commands from standard logic circuits. This makes it easier and more efficient to control the LED brightness level with the help of a control system such as a smart phone. It also enables users to easily control several LED modules with a single control circuit.

Working Principle

The CL325SG-G is a current-mode based LED driver. It receives an input voltage of 6-35 volts and converts it into a regulated output current that is sent to the LED module. The LED module then turns on and emits light. The LED driver monitors the output current and adjusts it to ensure the LED module works within its safe operating conditions.

In addition, the CL325SG-G offers protection and control functions to ensure the safety of the LED module. When the output current reaches its preset limit, the driver will reduce it to prevent the LED module from overheating. Likewise, when the output voltage reaches its upper limit, the driver will also reduce the current to prevent any additional damage to the module.

The CL325SG-G is a versatile and efficient PMIC with a range of features to meet the needs of a range of lighting applications. It provides a simple, reliable solution for driving and monitoring LEDs and offers excellent flexibility, reliability and energy savings.
