MAX1839EEP+

MAX1839EEP+ is an efficient electronic power control integrated circuit with multiple channels that efficiently regulate AC line power input to provide power to a variety of lighting applications such as high and low voltage lamps, electronic ballasts, and other power control applications. As a versatile and scalable IC, MAX1839EEP+ is designed to meet all global requirements for AC line harmonic distortion and transient response. This IC had been designed to dynamically control the power output of the connected device to meet global standards for RFI, EMI and power efficiency.

The Maxim Integrated’s MAX1839EEP+ was developed to provide a cost-effective alternative for ballast and lighting control applications. This IC has been designed to reduce power consumption, improves power factor, and reduces the AC line harmonic distortion. It provides high-level integration by integrating the entire power conversion and control circuitry on a single integrated circuit. By eliminating the need for external components, such as power switching devices, transformers, noise filters, and control circuits, the MAX1839EEP+ greatly reduces the cost and complexity of the system while enabling superior performance.

The MAX1839EEP+ provides eight channels of PWM modulated control of the connected device. The PWM modulation level is typically between 0V and 12V. The control signal generated by the IC uses a combination of frequency and pulse width modulation to accurately regulate the input power. Each channel is configured independent of the other and can be configured to generate any number of power output levels. The MAX1839EEP+ also provides fault protection, over-voltage and current-limiting protection, and thermal shutdown protection.

The MAX1839EEP+ features an internal voltage reference circuit, internal oscillator, and suitable control circuitry. The internal circuit provides a constant output voltage regardless of input voltage or load disturbance. The oscillator’s frequency is adjustable and drives the PWM modulated output signals. For each channel, the control circuitry monitors the input voltage, current and output voltage and outputs a range of PWM modulation levels to the connected device.

The Maxim Integrated’s MAX1839EEP+ is designed to reduce line harmonic distortion, improve power factor and efficiency, and reduce the cost of lighting and ballast control applications. By integrating all of the necessary power conversion and control circuitry onto a single IC, the MAX1839EEP+ simplifies the power conversion and control process while providing superior performance and reliability. This IC’s unique combination of features makes it an ideal solution for a wide range of AC line power control requirements.
