The FAN5702UC15X is a member of the highly integrated power management ICs (PMIC) family of LED drivers. It is an extremely efficient white LED (WLED) driver with integrated boost converter. The device is designed to provide high-current drive capability to power up white LEDs in LCD backlight application. It is an auto-dim detection device, with integrated auto-dim controller and current-mode architecture boost converter. The device is designed to provide years of power savings and enhanced brightness control to satisfy customer\'s LCD backlight requirements.

The FAN5702UC15X combines a highly efficient boost converter, optimally designed for LCD backlight applications with dim/brightness control. It also integrates a true linear dimming capability that includes a wide range of dimming control. This device can deliver programmable integrated current control and dimming performance from a single device. It is designed with an easy-to-use, low-cost solution for various LCD backlight applications.

The FAN5702UC15X is a single current-mode step-up converter that operates in a fixed frequency and delivers a regulated output voltage up to 19V. The device features a low startup current, high output accuracy, low supply current and low external components count. The device also features an active FET and soft-start, over-temperature protection, device reset and other features to ensure reliability and safety.

The FAN5702UC15X takes an input voltage of 2.7 V to 5.5 V and provides an adjustable output current of up to 15 A and a fixed output voltage of up to 19 V. The device is designed to operate effectively in the range of 10 to 14 V. The device is also capable of driving up to 8 white LEDs in series for each bank of LEDs. Furthermore, the device is equipped with thermal and current protection features to protect from over-current, over-temperature and output short-circuit conditions.

The working principle of the FAN5702UC15X is based on the current mode-control scheme. This device is a self-contained off-line boost converter and can be used to drive the white LEDs in LCD backlight systems. The device consists of an inductor connected between the input and output terminals, a switch that is controlled by the current mode feedback circuit and a power-on reset circuit. The device employs a feedback circuit that uses an internal current mirror to compare the output current to a reference current. When the output current exceeds the reference current, a signal is generated that is used to turn off the switch. This forces the output voltage to drop and brings the output current back to the reference value.

The FAN5702UC15X provides multiple protection features to continuously monitor the system. It features an over temperature, over current and an Enable signal protection. This device is designed to drive up to 6 strings of 8 LEDs in parallel for each bank of LEDs inversely with the logic control. The device also features clock synchronization and auto dimming control capability. It also includes a built-in thermal shutdown circuit to protect against device over-temperature.

The FAN5702UC15X is an ideal power management solution for LCD backlight applications. Its highly integrated design and dimming capability make it an excellent choice for a wide range of LCD backlight applications. Its high efficiency and low power consumption make it an ideal choice for power saving applications.
