TS19378CS RLG

LED Drivers are power management integrated circuit (PMIC) devices used to control and regulate the current to a light emitting diode (LED). They offer a range of benefits such as, improving the efficiency of LED’s and prolonging the life of the LED, by providing a means of regulating the heat generated by the LED. The TS19378CS RLG is a highly efficient linear current regulator with a selectable operating voltage range of 14.7V to 20V. It provides easy current adjustment and features adjustable switching frequency, low quiescent current, and a wide range of protections, making it ideal for general illumination applications.

For a more efficient power management, this device is designed with an integrated current mirror, bypass circuit, and a high-side current sensing circuit. The integrated current mirror circuit ensures that the LEDs are always driven at the same current. The bypass circuit, on the other hand, allows the low side driver to operate at the steady state regardless of the input voltage. This helps the device to provide a high level of efficiency and accuracy in controlling the output current.

The device is also designed with a low quiescent current mode for energy savings. The quiescent current is reduced to 10µA when the device is in this mode, reducing the overall power consumption. Additionally, the TS19378CS RLG features adjustable switching frequency, allowing users to adjust the frequency of the switch to optimize the efficiency of the system. This helps users reduce switching losses and conserve energy.

To ensure the light output is stable regardless of the input voltage, the TS19378CS RLG features overvoltage, temperature, and current protections. Overvoltage protection ensures the output voltage remains under the specified limit, while temperature protection monitors the LED temperature and prevents it from exceeding the maximum limit. Current protection detects over-current conditions and keeps the LED current at a safe level.

The TS19378CS RLG is an ideal linear current regulator for general illumination applications. Its integrated current mirror and bypass circuit, adjustable switching frequency, low quiescent current, and a wide range of protections make it an ideal choice for LED lighting applications. The device offers an efficient, accurate and reliable means of controlling the current to the LED, taking into account all the necessary protections and safety features, thus making it a perfect choice for lighting applications.
