Application fields of LV5217GP-TE-L-E include both indoor lighting and street lighting solutions. It can fulfill applications for measuring instruments, medical equipment, automotive lighting, automotive gauges, television backlighting or other display applications. The combination of a low quiescent current and low output voltage make LV5217GP-TE-L-E an ideal choice for low power LED applications.

LV5217GP-TE-L-E is an LED driver based on linear LED current controller, designed with an integrated current-sense amplifier and regulator voltage. Compared to the traditional current feedback loop, this driver provides a higher switching frequency and improved linearity of current control. It also provides a low quiescent current, excellent efficiency and allows direct driving of multiple LEDs.

The basic working principle of LV5217GP-TE-L-E is that the current mode loop of the driver detects the voltage drop across the current sense resistor or sense inductor in the external part of the circuit. This voltage is compared against a reference voltage from the reference setting, and the error amplifier then adjusts the PWM signal to keep a constant current through the LED string. This ensures that the LED string is driven with a precise amount of current, as specified by the user.

In conclusion, LV5217GP-TE-L-E is a high-efficiency and cost-effective LED driver for controlling large LED arrays. It uses linear LED current controller for improved linearity and high switching frequency. The driver provides low quiescent current and excellent efficiency, allowing direct driving of multiple LEDs in applications such as automotive lighting, medical equipment, television backlighting, and other display applications.
