UC2572DTR Description

Short technical summary and product information.

The UC2572DTR from Texas Instruments is a negative output flyback pulse width modulator. It is optimized for use in single inductor flyback switching converters employing an external PMOS switch. This device converts a positive input voltage to a regulated negative output voltage.

 

Key electrical specifications include an operating voltage range of 4.75V to 30V and a typical operating frequency of 100kHz. It supports a maximum duty cycle of 92% and features control functions such as current limit and ramp. The output configuration is negative, and it functions as a step-up/step-down converter.

 

Designed for surface mount applications, the UC2572DTR comes in an 8-SOIC package. It includes an undervoltage lockout circuit and pulse-by-pulse current limit. The device also features a low sleep mode current of 50µA, making it suitable for battery-powered applications.

 

Environmental compliance includes RoHS3 compliance and an MSL rating of 1. The operating temperature range is -40°C to 85°C.
