The UC2879N from Texas Instruments is a phase shift resonant controller designed to manage bridge power stages. It facilitates constant frequency pulse width modulation combined with resonant, zero-voltage switching for high efficiency.
This controller is compatible with voltage mode or current mode topologies and can operate at switching frequencies up to 300 kHz. Key features include a programmable output turn-on delay, zero delay availability, and independently programmable time delays for dead-time control. It also incorporates an undervoltage lockout and overcurrent shutdown for fault protection.
The UC2879N is suitable for applications requiring efficient power conversion. It features a 10-MHz error amplifier and a 5V precision reference. The device supports soft start control and has outputs that are active low during UVLO.
Packaged in a 20-DIP format, the UC2879N is designed for through-hole mounting. It operates within a temperature range of -40°C to 85°C.
