OP Amps, Buffer Amps ICs

The Texas Instruments TL3472CDR is a high-precision, low-power, 12-bit PWM constant current/constant voltage step-up/step-down LED driver with a built-in power MOSFET. It is designed to provide efficient and reliable control for LED lighting applications.

Description:

The TL3472CDR is a monolithic LED driver that integrates a power MOSFET, error amplifier, current sense circuitry, and a PWM controller. It operates with an input voltage range of 4.5V to 40V and can output a constant current of up to 3A. The device features a programmable output current and output voltage, allowing for precise control of the LED brightness and color.

Features:

1. High-precision constant current and constant voltage control
2. Wide input voltage range (4.5V to 40V)
3. Programmable output current and output voltage
4. Integrated power MOSFET
5. Low quiescent current (<1.5mA)
6. High efficiency (up to 95%)
7. Small package size (8-pin SOIC)

Applications:

1. LED lighting for automotive applications (headlights, taillights, interior lighting)
2. LED lighting for industrial and commercial applications (work lights, display lighting, architectural lighting)
3. LED lighting for outdoor applications (streetlights, floodlights, landscape lighting)
4. LED lighting for consumer electronics (TV backlights, monitor backlights, notebook backlights)
5. LED lighting for medical and dental applications (surgical lamps, dental examination lamps)

The TL3472CDR is a versatile and efficient LED driver that can be used in a wide range of applications requiring precise control of LED brightness and color. Its high efficiency, low quiescent current, and small package size make it an ideal choice for space-constrained and power-sensitive applications.
