XR46701IRBTR

PMIC - LED Drivers

The XR46701IRBTR is an LED driver integrated circuit that is used in application areas such as LED lighting and signal illumination. The circuit is a resistive-switched step-down converter with high-efficiency, low-noise, and fast response.

Working Principle

The XR46701IRBTR is a step-down converter that is used to provide a stabilized output voltage from an input voltage. The input voltage is supplied to the converter’s primary switch, while the output of the converter is supplied to the converter’s secondary switch. The primary switch is controlled by the control circuit, which adjusts its duty cycle so that the output voltage is maintained at the desired level.

The control circuit monitors the output voltage and adjusts the duty cycle of the primary switch accordingly. When the output voltage is too low, the duty cycle of the primary switch is increased, which increases the amount of current being sent to the output switch. When the output voltage is too high, the duty cycle of the primary switch is decreased, reducing the amount of current being sent to the output switch.

Applications

The XR46701IRBTR circuit is used in a wide range of applications, such as automotive lighting, emergency lighting, stage lighting, and backlighting. In these applications, the XR46701IRBTR provides a highly efficient and reliable method of powering high-intensity LEDs.
