Supervisors

The Texas Instruments TPS3840DL22DBVR is a high-performance, monolithic, step-down (buck) switching regulator that is designed to provide efficient power conversion in a wide range of applications. It is available in a compact, thermally enhanced, dual flat no-lead (DFN) package.

Description:

The TPS3840DL22DBVR is a highly integrated, high-efficiency, synchronous step-down converter that can operate from a wide input voltage range of 4.5V to 23V. It is capable of delivering up to 2A of continuous output current with high efficiency and low quiescent current. The device features a low dropout (LDO) regulator, which provides a stable and accurate output voltage for applications that require a low-noise power supply.

Features:

1. Wide input voltage range: 4.5V to 23V
2. High efficiency: up to 95% efficiency
3. High output current: up to 2A
4. Low quiescent current: 3.5μA in ultra-low-quiescent-current (UQ) mode
5. Low dropout (LDO) regulator for low-noise power supply
6. Integrated power MOSFETs with low RDS(on)
7. Programmable soft-start and output voltage tracking
8. Over-current protection, over-temperature protection, and thermal shutdown
9. Small and thermally enhanced DFN package

Applications:

The TPS3840DL22DBVR is suitable for a wide range of applications that require efficient power conversion and regulation. Some of the key applications include:

1. Industrial and automotive systems
2. Portable electronic devices, such as smartphones, tablets, and wearables
3. IoT devices and smart home appliances
4. Medical equipment and devices
5. Telecommunication equipment
