PMIC - LED Drivers
The LM2753SD/NOPB is an integrated topology power management integrated circuit (PMIC) designed to efficiently and accurately provide the necessary voltage and current to direct drive white LEDs. This integrated circuit is part of a family of Texas Instruments PMICs that are optimized for the operation of LEDs and linear current regulation for lighting applications. This device is capable of operating in constant current, constant power, or constant voltage modes allowing a wide range of LED topologies and power levels to be driven.
The LM2753SD/NOPB provides a simple, single-chip solution for driving LEDs in applications including lighting, automotive, and portable devices. This PMIC offers a fast current ramping and settling periods, as well as flexible operation in various modes, and provides a method for controlling the LED power supply current, voltage, and on/off control without the need for additional external components.
The LM2753SD/NOPB is a low power, low output current, low voltage, and single-chip integrated circuit. It features a 0.7V to 4.5V adjustable output voltage, a 0.5A to 3.3A adjustable output current, and a 0.25% high accuracy current regulation. Additionally, it offers an adjustable gain, adjustable voltage, and adjustable frequency. This PMIC has an on/off time of 1ms and a standby current of less than 100µA.
The LM2753SD/NOPB operates in three different modes: constant current, constant power, and constant voltage. In constant current mode, the LED current is regulated precisely and independent of the changes in voltage. In constant power mode, the LED power is regulated precisely and independent of the changes in voltage. And in constant voltage mode, the output voltage is regulated precisely and the LED current is set by the internal resistance at the output.
The LM2753SD/NOPB also offers a slew of digital and analog features. The digital features include an output-enable pin, thermal shutdown circuitry, and a power-on reset circuit. The analog features include an adjustable current limit, an adjustable gain, and an adjustable voltage. The LM2753SD/NOPB also features a slew of protections, including open-circuit protection, over-current protection, reverse-voltage protection, and thermal modulation.
In brief, the LM2753SD/NOPB is a highly integrated PMIC designed specifically for driving LEDs in a variety of applications. It provides the output voltage and current regulation required to control white LEDs, with the added benefit of low-power consumption, fast current ramping and settling, and adjustable gain and voltage. With its various digital and analog features, the device is suited for a wide range of LED topologies and power levels.
