External/Internal LED Drivers

The LM2755TMX/NOPB is a high-efficiency step-down (buck) switching regulator from Texas Instruments. It is designed to provide a stable and regulated output voltage from a wide range of input voltages. Here is a description of the model, its features, and applications:

Description:

The LM2755TMX/NOPB is a monolithic step-down switching regulator that uses a constant-frequency current mode control scheme. It is available in a thermally enhanced 20-pin 4mm x 5mm PowerSO package. The device is designed for applications requiring a high level of efficiency and performance.

Features:

1. Wide input voltage range: 4.75V to 38V
2. Fixed 5V or adjustable output voltage
3. High efficiency: up to 94% depending on the input voltage and output current
4. Low quiescent current: 150µA (maximum)
5. Adjustable switching frequency: 150kHz to 1MHz
6. Internal soft-start and current limiting
7. Over-temperature and over-current protection
8. Small package size: 4mm x 5mm PowerSO package

Applications:

1. Power supply for portable devices: smartphones, tablets, and laptops
2. Power supply for low-power LED lighting applications
3. Power supply for small form-factor industrial and consumer electronics
4. Power supply for battery charging applications
5. Power supply for IoT devices and sensors

The LM2755TMX/NOPB is a versatile and efficient step-down regulator that can be used in a wide range of applications where a stable and regulated output voltage is required. Its high efficiency and small package size make it an ideal choice for compact and power-sensitive applications.
