Introduction to STP16CPPS05TTR LED Driver
STP16CPPS05TTR is an LED driver integrated circuit, specifically designed for the Enhancement Mode Field-Effect Transistor (E-MOSFET) current-regulating power switch and Boost converter circuits. It is part of the PMIC – LED Drivers family, and offers multiple features that makes it a powerful yet cost-effective solution for providing constant-current drive for outer LED front-lighting/backlighting.
Application Field and Working Principle
STP16CPPS05TTR can be applied in all kinds of displays, such as mobile phones, digital appliances and other device applications. It provides all the necessary circuitry for constant-current output regulation and Boost power converter, and is especially intended for driving single-color LED strings. It can also be used to drive two-color LED string with individually regulated constant-current, or in multi-tasking applications as direct voltage regulator, or single point ground converter.
It works with two main operating modes: DC/DC converter mode and PFM operation mode. In DC/DC converter operating mode, the switching cycle over a given period can be adjusted according to the input supply voltage. PFM operation mode adjusts the output current inversely proportional to its input voltage by varying the switching cycle in order to maintain a constant output current. The constant output current is adjusted by an external shunt network.
STP16CPPS05TTR provides a wide range of features to increase efficiency and reduce power consumption. Firstly, it has an adjustable over-voltage protection that senses an excessive output voltage, and disconnects the LED load from the input supply. Secondly, it has an adjustable input voltage detection, which helps prevent low voltage from damaging the LED driver. Thirdly, it features an adjustable soft-start, which prevents an inrush current surge when lighting the LED, and fourthly, it features thermal shutdown protection, which protects the LED driver from overheating.
In addition to its extensive range of features, STP16CPPS05TTR is also compatible with both synchronous and asynchronous Boost converters. Furthermore, it provides a high gate slew-rate driving capability and very low current consumption. In addition, it also supports various dimming control modes, such as Pulse-Width Modulation (PWM), Analog Volt-Time (AVT) and Resistive Dimmers (RD).
Conclusion
STP16CPPS05TTR stands out as a powerful yet cost-effective PMIC – LED Driver IC, specifically designed to provide constant-current drive for outer LED front-lighting/backlighting. It benefits from a wide range of features, such as adjustable over-voltage protection, adjustable input voltage detection, adjustable soft-start, and thermal shutdown protection. Furthermore, it is compatible with both synchronous and asynchronous Boost converters, and is capable of supporting various dimming control modes. In conclusion, STP16CPPS05TTR is a great option for powering LED displays.
