UCC2960 Description

Short technical summary and product information.

The Texas Instruments UCC2960 is a primary-side startup controller specifically designed for single-ended, isolated offline switch-mode power converters that utilize secondary-side PWM control. This IC provides all necessary primary-side functions, making it suitable for systems requiring sophisticated overload condition handling.

Key electrical specifications include a synchronizable switching frequency of up to 400 kHz, a high-current FET drive capability of 1.5-A sink and 0.75-A source, and an undervoltage lockout feature with 2-V hysteresis. It also supports initial free-running soft-start up with duty-cycle clamping and low-current startup.

The UCC2960 is available in 8-pin SOIC (D) and PDIP (P) packages. Its design facilitates the use of a simple, low-cost isolating pulse transformer for transmitting PWM commands, enabling higher converter bandwidth and simplifying load monitoring and control.

This controller is well-suited for applications where precise control over power conversion is needed, especially in isolated power supply designs. It integrates essential primary-side circuitry, simplifying the overall power supply architecture.
