CP8146AT

The CP8146AT is a high-performance, single-chip, step-down (buck) switching regulator from Infineon Technologies. It is designed to provide efficient and stable power conversion for a wide range of applications.

Description:

The CP8146AT is a compact, high-efficiency switching regulator that can handle input voltages from 4.5V to 22V and deliver an output voltage as low as 0.9V. It features a high switching frequency of up to 2MHz, which allows for the use of smaller external components and more compact designs. The device is available in a small, thermally enhanced, 5x6mm QFN package.

Features:

1. Wide input voltage range: 4.5V to 22V
2. Low output voltage: down to 0.9V
3. High efficiency: up to 95% depending on the input voltage and output current
4. High switching frequency: up to 2MHz
5. Small package size: 5x6mm QFN
6. Internal soft-start and current limiting for protection
7. Low quiescent current: less than 50µA in no-load condition
8. Low dropout voltage (LDO) mode for improved efficiency at light loads
9. Over-current protection, over-temperature protection, and thermal shutdown

Applications:

The CP8146AT is suitable for a variety of applications that require efficient and stable power conversion, including:

1. Portable devices: smartphones, tablets, and wearables
2. Power banks and battery chargers
3. IoT devices and smart home applications
4. LED lighting and drivers
5. Industrial and automotive systems
6. Medical devices and equipment
7. Telecom and networking equipment

The CP8146AT's high efficiency, wide input voltage range, and low output voltage make it an ideal choice for designers looking to optimize power conversion in their applications.
