PMIC-LED Drivers
The SSL2129AT/1J is a Pulse Width Modulation (PWM) controller that is capable of PWM dimming control for LEDs in automotive and industrial applications.
The SSL2129AT/1J is designed for use in applications such as automotive interior lighting, exterior lighting and panel lighting programs, as well as industrial applications including warning beacons and strobes. The unit requires only a few external components including a dummy backlight capacitor, an external circuit to generate the PWM signal and an outside resistor to set the maximum range of 10V.
The SSL2129AT/1J has an adjustable dim-out frequency and can drive any type of LED, including high power white, colored and ultra high brightness (UHB) LEDs. The SSL2129AT/1J works with input voltages up to 75V and power ratings up to 250W, making it suitable for automotive and performance LED applications.
Features of SSL2129AT/1J
The SSL2129AT/1J offers a range of features, including:
- A wide range of PWM dimming ratios to control both brightness and color.
- High efficiency, up to 95% in PWM low-light mode.
- Flexible PWM dimming frequency range.
- Temperature protection mode.
- Low dropout voltage.
- High-current load capability.
- High current switching speed.
- Low noise operation.
- High speed startup.
- Built-in fault detection.
- Compact size.
Working Principle
The SSL2129AT/1J uses a PWM technique to control the brightness and color of an LED. The PWM signal is generated by an outside circuit and is applied to the SSL2129AT/1J. The SSL2129AT/1J then amplifies the signal and delivers a high-power PWM waveform to the LEDs. The waveform is a combination of on-times and off-times, with the on-times determining the brightness and the off-times determining the color. The SSL2129AT/1J is able to adjust the on-times and the off-times to achieve dimming and color regulation.
The SSL2129AT/1J also includes temperature protection circuitry, which is used to protect the LEDs from high temperatures. If the temperature of the LEDs exceeds the preset protection limit, the SSL2129AT/1J will reduce the output power to prevent damage. The SSL2129AT/1J also features an over-temperature protection circuitry, which will shut off the output in case of an Over Temperature Protection event.
Applications
The SSL2129AT/1J is ideal for use in a variety of automotive and industrial LED lighting applications, including:
- Automotive interior, exterior and panel lighting.
- Industrial warning beacons and strobes.
- High-power white and colored LED lighting.
- Ultra high brightness LED lighting.
- Emergency vehicle lighting.
The SSL2129AT/1J is also suitable for applications such as off-road lighting, landscape lighting, stage lighting and special effects. The unit is easy to implement, requires low external component count and is available in leaded and lead-free packages.
Conclusion
The SSL2129AT/1J PWM controller from NXP is a versatile device that provides exceptional performance and features in a small and compact package. The unit is designed for optimal performance in automotive and industrial LED applications, and offers a wide range of PWM dimming ratios with high efficiency, temperature protection and low power consumption. The SSL2129AT/1J is easy to implement, requiring only a few external components, making it suitable for a variety of LED lighting applications.
