UC2842BD1R2G  

DC DC Switching Controllers

The UC2842BD1R2G is a high-voltage, fixed frequency, current mode control step-down switching regulator integrated circuit (IC) manufactured by ON Semiconductor. It is designed to provide efficient and stable power conversion in a wide range of applications.

Description:

The UC2842BD1R2G is a monolithic integrated circuit that provides all the active functions required to implement a step-down switching regulator, also known as a buck converter. It features a fixed 500kHz switching frequency, which allows for the use of smaller external components and simplifies the design of the power supply.

Features:

1. Fixed 500kHz switching frequency
2. High-voltage operation up to 40V
3. Current mode control for improved transient response and stability
4. Internal soft-start and current limiting for protection against overcurrent conditions
5. Thermal shutdown protection to prevent damage due to overheating
6. Enable/disable input for easy control of the regulator
7. Synchronous rectification for improved efficiency at light loads
8. Small package size (SOIC-8 or MSOP-8)

Applications:

The UC2842BD1R2G is suitable for a wide range of step-down power conversion applications, including:

1. Desktop and laptop computer power supplies
2. Industrial control systems
3. Telecommunications equipment
4. LED lighting systems
5. Battery chargers and power banks
6. Medical equipment
7. Automotive electronics

The UC2842BD1R2G's high-voltage operation, fixed switching frequency, and current mode control make it a versatile and reliable choice for designers looking to implement efficient and stable step-down power conversion in their applications.
