UCC2804DTR

The UCC2804DTR is a high-voltage, high-current, single-ended primary inductor converter (SEPIC) from Texas Instruments. It is designed for use in a variety of applications, including motor control, battery charging, and power supply systems.

Description:

The UCC2804DTR is a monolithic power converter that integrates a high-voltage power MOSFET, a controller, and other support components onto a single chip. It operates in a single-ended primary inductor converter (SEPIC) configuration, which allows it to convert input voltage to a regulated output voltage that can be higher, lower, or equal to the input voltage.

Features:

• High-voltage operation: The UCC2804DTR can operate with input voltages up to 60V.
• High-current capability: The device can handle output currents up to 3A.
• Wide input voltage range: It can operate with input voltages from 4V to 60V.
• Fixed 5V or adjustable output voltage: The output voltage can be set to a fixed 5V or adjusted using an external resistor divider.
• Soft-start function: The soft-start feature limits the inrush current during startup.
• Overcurrent protection: The device provides overcurrent protection to prevent damage to the power supply or load.
• Thermal shutdown: The UCC2804DTR includes a thermal shutdown feature that disables the device if the temperature exceeds a safe operating limit.
