OPA779D-11646 Application Field

The OPA779D-11646 is most commonly used to control and operate LED lighting, ranging from basic lighting for residential and commercial construction to complex lighting for big theater stages and movie sets. This device can be used for both indoor and outdoor lighting, so long as the ambient temperature does not exceed the device’s maximum operating temperature. Additionally, the OPA779D-11646 can be used to control the brightness and color of LED products, creating diverse applications for dynamic video effects, such as color changing, strobe lighting, and others.

The OPA779D-11646 can also be used in other applications aside from LED lighting. It is commonly used in addition to the OPA390 to power up other types of high-intensity lighting, such as Linear Fluorescents and High-Intensity Discharge (HID) lamps. All types of lighting systems require some type of control circuitry, making the OPA779D-11646 an ideal choice for a variety of applications.

Beyond lighting, the device can be used to control other electronic components. The OPA779D-11646 can be used to regulate motor speed, such as in electric motors, and stepper motors, or it can be used to regulate voltage from a DC source. Additionally, the device can be used to control the current passing through a resistor or a ferrite inductor, or to regulate the temperature in a heating or cooling system.

OPA779D-11646 Working Principle

The OPA779D-11646 is a non-isolated buck regulator that uses pulse-width modulation (PWM) to control the voltage output. The device contains several components that regulate the output voltage, including an input voltage regulator, output voltage regulator, and an embedded chipset. The device takes an input voltage range of 4.5 to 25 volts DC and outputs a variable voltage range of 0.2 to 3.3 volts DC. The OPA779D-11646 is designed to allow the user to adjust the output voltage and power levels by setting two potentiometers – one to set the basic output voltage, and another to adjust the voltage margin.

To control the output voltage, the device first passes the input voltage through an input regulator, which is used to stabilize the voltage to an appropriate level. The input voltage is then converted to a Pulse-Width Modulated (PWM) signal. This signal is transmitted to the output voltage regulator, where the output voltage is adjusted based on the duty cycle of the PWM signal. The device is then able to control the voltage output to the desired levels.

The OPA779D-11646 also includes an embedded chipset that stores a set of adjustable parameters. These parameters can be adjusted based on the user’s requirements, and they govern how the device will respond to various input voltages and temperature fluctuations. Additionally, the device is designed to protect against input overvoltage, output overvoltage, and short-circuits.

The advantages of the OPA779D-11646 include its compact size, versatility, and programmable output voltage and power levels, allowing for a variety of applications in LED lighting, as well as other electronic components. In addition, it has a wide input voltage range, making it suitable for a variety of power sources, such as batteries and solar panels. Additionally, the device is designed to be highly efficient, so it can be used in applications where power efficiency is important.

In conclusion, the OPA779D-11646 is a versatile and simple-to-use device that can be used in a variety of LED lighting applications as well as many other electronic components. Its features allow for adjustable output voltage and power levels, and it can be used with a wide range of input voltage sources. Additionally, the device is highly efficient, making it the perfect choice for any lighting project.
