MAX16814AUP/V+ is a high-precision, high-integration, wide-input (2.9V to 38V) high-efficiency (up to 93%) small-sized, and low-noise White LED (WLED) Charge Pump Converter that falls in the category PMIC - LED Drivers. The device is intended to drive up to 8 strings of LEDs allowing systems to save board space by reducing the need for multiple inductors and provides the flexibility for variable light output. It employs a buck-boost architecture and can operate at 2000 kHz or Forced PWM Mode.

The MAX16814AUP/V+ has many advantages, such as allowing the user to individually regulate the current for each string, and providing two External Brightness Control (EBC) options, one of them being an external Step Down converter that allows either the voltage level or the output current of the device to be modulated ranging from 2.9V to 8V or 2 mA to 25 mA respectively. Other features include improved accuracy and efficiency, Open LED Detect (LED open circuit protection) and PWM dimming capability. The device also has Short LED Open Detect (SLOD) and Short LED-to-Battery (LSB) Detect.

The application field of MAX16814AUP/V+ includes LED-backlight display, LED lighting, LED-backlighting industrial and automotive displays, LED light box advertisement and so on. The device is highly suitable for any application that requires precise LED current control each LED string, reduced BOM count and custom output current and voltage level.

To understand how MAX16814AUP/V+ works, it is important to understand different parts of the device. The MAX16814AUP/V+ is based on a buck-boost architecture. The device has two switches, the top switch and the bottom switch. The top switch is connected to the battery, while the bottom switch is connected to ground. When the device is powered, both switches will be “on”. During this period, the battery voltage is converted to a higher voltage and the output voltage is generated. When the battery voltage drops, the bottom switch will be turned off and the top switch will remain on, allowing the device to “step-up” the battery voltage. The device will continue to step-up the battery voltage until it reaches the desired level.

In conclusion, MAX16814AUP/V+ is a key device for LED drivers, allowing for a wide-input voltage and current regulation for each LED string. It is a high-efficiency, small-sized and low-noise device, suitable for LED-backlighting, LED lighting, LED light box and other industrial applications. MAX16814AUP/V+ is a good choice for those who require precise LED current control, smaller BOM counts and adjustable output current and voltage level.
