The TPS92602BQPWPRQ1 is a power management integrated circuit (PMIC) that belongs to the family of LED drivers. It offers a comprehensive set of features and functions to power and protect single, dual and multiple LEDs in white, RGB, or RGBW single or multiple arrays. It is ideal for lighting designs with multiple inputs and up to 24-string LEDs. Among the features of this device include boost converter with lowest RDSON, SPI/PWM control, active current balancing, open LED/short LED/LED overtemperature protection, current monitoring, short-circuit protection, adjustable VDD and soft-start.

The TPS92602BQPWPRQ1 is applicable in a wide range of personal portable and consumer electronic applications, including LED signs, LED displays, LED flashlights, LED decorative lighting, LED clusters, LED tubes, LED TV backlights, mobile phones, digital cameras, camcorders, LCD display panels, notebook and netbook computers, portable radar systems, and set-top boxes.

Its working principle is based on a boost topology with integrated internal power switches. This device has a low voltage input range that makes it suitable to achieve the high output current required to power white LEDs. The TPS92602BQPWPRQ1 alleviates designer\'s requirement of settling the complex external components, such as startup inductor, catch diode, small ceramic output capacitor, exposed pad thermal conductive pad, and dual-shunt resistor.

The TPS92602BQPWPRQ1 operates in discontinuous conduction mode (DCM). DCM maximizes efficiency on applications with varying input power, requires no external compensation to secure system stability, and extends battery life. It has an adjustable operating frequency of up to 1MHz and output voltage adjustable from 40V to 64V with ±2% accuracy (typical). Additionally, the device has programmable soft-start and over-temperature protection that prevents damage to LEDs.

Furthermore, the TPS92602BQPWPRQ1 is provided with active-current balancing and monitoring functions. The current sense amplifier works as a current comparator and monitors the current level through the external dual-shunt resistors. An overcurrent condition is detected when the voltage difference is greater than a must-trigger voltage between the two resistors. Instruction sets support the implementation of the PWM function, enabling simultaneous control of the on/off and dimming of each LED channel. Along with this, it comes with an Error Amplifier feedback that ensures user to regulating the output voltage individually.

Overall, the TPS92602BQPWPRQ1 is an impressive PMIC for LED driver designs. It is suitable for a wide range of applications and offers various features and functions, including boost converter with lowest RDSON, SPI/PWM control, active current balancing and monitoring, open LED/short LED/LED overtemperature protection, adjustable VDD and soft-start. It can easily meet the demands of high power LED applications in the consumer market.
