PMIC - LED Drivers

A LED driver is a self-contained power supply which has outputs that are specifically designed to match the electrical characteristics of a LED or a string of LEDs. LED drivers can be broadly divided into two categories, linear and switch-mode, based on the type of switching technology used. CS1610A-FSZR is a linear LED driver.

Application field

CS1610A-FSZR is widely used in LED lighting applications, such as LED indoor lighting, LED street lighting, LED track lighting and so on. It provides power ranging from 1W to 10W per string, and can drive 2 to 8 strings in parallel. CS1610A-FSZR is an ideal choice for applications requiring dimming, as it supports analog dimming and also PWM dimming. It also has a wide dimming range (up to 16 bits).

Working principle

The CS1610A-FSZR is a linear current sink driver, which means that the output current is set based on the voltage applied to its control input pin. This voltage is usually generated from an external PWM signal. When the control pin voltage is low, the output is off, and when the control pin voltage is high, the output is at a constant current level determined by the resistor connected to its feedback pin. By changing the control pin voltage, the output current level can be varied.

The CS1610A-FSZR has a wide input voltage range, from 4V to 40V, which means that it can be used for various applications. It also has an adjustable output current range from 0A to 10A and an adjustable voltage range from 0V to 24V. The CS1610A-FSZR can also detect a short circuit between its output and the LED, and will automatically shut off the power in such a situation.

Conclusion

The CS1610A-FSZR is a linear LED driver which can be used in a wide range of LED lighting applications. It provides a wide input voltage range, adjustable output current range, and adjustable voltage range. It can also detect a short circuit, and will shut off the power automatically if it is detected. The CS1610A-FSZR is an ideal choice for applications requiring dimming, as it supports both analog and PWM dimming.
