CAT4103AGEVB Datasheet/PDFEvaluation Boards - LED Drivers
The CAT4103AGEVB application field and working principle is a type of LED driver used in evaluation boards. It is used to drive small and large LED arrays.
Features
- High-efficiency PWM constant-current LED driver.
- On-board adjustable pin output current.
- Drive up to 35 LEDs.
- Wide operating temperature range of -40°C to +85°C.
- Programmable maximum output power.
- Programmable minimum output current.
Functionality
The CAT4103AGEVB application field and working principle can drive up to 35 LEDs and provides an adjustable, constant current output. It can be programmed to turn the LEDs on and off — this is done by programming the minimum and maximum output current.
The CAT4103AGEVB is also suitable for use in applications that require short bursts of current, such as automotive lighting, hand held devices and lighting system design. The device also features open-drain and push-pull configurations, flexible architecture to reduce the number of external components and enable integration of complex lighting solutions.
Applications
- Headlights and tail lights.
- Displays and signage.
- Backlighting.
- Indoor/outdoor lighting.
- Automotive infotainment equipment.
Working Principle
The CAT4103AGEVB application field and working principle uses PWM constant-current LED driver. The operating frequency of the PWM is adjustable from 500 kHz to 3 MHz and the output current is adjustable from 25 mA to 350 mA. The output current is user-programmable, and is adjustable with the on-board adjustable pin.
Conclusion
The CAT4103AGEVB application field and working principle is a versatile LED driver with many features, including adjustable maximum output power, adjustable minimum output current and a wide operating temperature range of -40°C to +85°C. It is suitable for driving up to 35 LEDs and is suitable for a wide range of applications, such as headlights and tail lights, displays, signage, backlighting and automotive infotainment equipment.
