LP55271TL/NOPB is a compact, programmable highly integrated power management integrated circuit (PMIC) with LED drivers. The device is focused on providing proven solutions for light-emitting diode (LED) lighting applications in which maximum design flexibility and minimum design efforts are essential. It is particularly suitable for applications such as cell phones, tablets and TV backlighting.

The LP55271TL/NOPB contains a number of powerful features that provide designers with an effective solution for controlling LED lighting. It includes four dedicated 16-bit variable current drivers for maximum flexibility and control. Each individual LED channel can be programmed to different current values or can be synchronized or used in pulse width modulation (PWM) mode. The device also contains an internal I2C (Inter-Integrated Circuit) interface that provides a convenient way to configure several parameters.

The LP55271TL/NOPB is powered by a wide input voltage range from 2.7 V up to 9 V and provides an output voltage from 0.2 V up to 5 V. Its current output can be programmed from 0 to 50 mA for each channel. Its built-in EEPROM memory allows it to store up to 32 individual profiles or sequences of LED control, which can be invoked by commands sent over the I2C bus.

The LP55271TL/NOPB contains an LP5562EL internal I2C slave logic to identify commands from the control system and to interpret and execute them. The device is task-oriented and allows users to set up one of several user-defined tasks to tailor the commanded operation to a particular requirement. The LP5562EL\'s flexible output configuration options enable designers to create a wide range of pre-programmed or customizable light displays using the device.

The LP55271TL/NOPB includes an integrated real-time clock (RTC) for time-based LED control. This feature allows users to set up various time-based patterns and simplify the programming procedure. The device also includes a low-voltage detection that can be used to detect battery depletion to protect LEDs from over-current situations.

LP55271TL/NOPB also includes an internal voltage regulator that can be used to enable a wide range of programming voltages from 1.2V to 6V. This feature allows designers to optimize the power efficiency and minimize power losses in the device.

The LP55271TL/NOPB offers a 12-bit programmable PWM signal along with two individual, programmable general-purpose bits. The signal can be used to program and control different aspects of the device. It can be used to dim LED channels, set LED brightness levels or set LED color temperature. The two general-purpose bits can be used to program additional LED control functions, such as LED blinking, fading or pulsing.

The LP55271TL/NOPB is the ideal device for any LED lighting application, such as automobiles and backlighting. Its features make it a powerful and reliable device, capable of providing fast and efficient control of LEDs with minimum design efforts.
