PMIC - LED Drivers technology has been developed as a way of improving the brightness and efficiency of LEDs while also creating a more uniform level of brightness. The AP3602BKTR-E1 is an ultra-high power LED driver designed to address the application field and working principle of LED backlighting. The device features zero current start and stepped dimming control, enabling improved design reliability and high efficiency in a wide range of LED lighting solutions.

The AP3602BKTR-E1 works by driving each LED channel with a constant regulated current, eliminating the need for complex dimming via pulse width modulation (PWM) or analog voltage control. The device’s inherent dimming control feature is based on the pulse-width-modulation (PWM) dimming principle with bidirectional brightness adjustment. This eliminates the hassle of manual PWM dimming or analog voltage control by providing a better light output curve with fewer dimming steps.

The AP3602BKTR-E1 is highly efficient, with a maximum operating efficiency of 94%. The device supports a wide input voltage range – from 3.3V to 28V – that is compatible with a variety of LED drivers, including white LED chips and LED arrays. It also features a maximum LED current of 365 mA, which enables it to support a total LED current load up to 1.5A.

The AP3602BKTR-E1 is designed with a high output current accuracy of ±5.5%, eliminating any noticeable variation in brightness caused by current mismatch among LEDs. This eliminates hot spots and other problems associated with current mismatch, allowing for better light control and uniformity.

The AP3602BKTR-E1 also makes it easier for LED backlighting designers to achieve zero current startup by simply disabling the PWM signal. This eliminates the need for complex dimming circuits and other components, reducing the overall cost of LED backlighting design.

The AP3602BKTR-E1 is ideal for use in a wide variety of applications, including LCD backlighting, automotive applications, and illumination lighting. The device has a wide range of operating temperature and is certified for use in applications where operating temperatures reach up to 125°C.

Overall, the AP3602BKTR-E1 is an ideal solution for meeting the application field and working principle of LED backlighting. It provides consistent power delivery with high efficiency and zero current start, making it ideal for a wide variety of LED backlighting applications.
