The UC2879DWTRG4 from Texas Instruments is a phase-shift resonant controller designed to manage a bridge power stage. It facilitates constant frequency pulse width modulation in combination with resonant, zero-voltage switching for high efficiency.
This controller is compatible with voltage mode or current mode topologies and offers practical operation at switching frequencies up to 300 kHz. Key electrical features include a programmable output turn-on delay, zero delay availability, and a 10-MHz error amplifier for fast fault protection. It also incorporates undervoltage lockout and soft start control.
The device is housed in a 20-SOIC package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C (TA) and supports a supply voltage from 9.25V to 20V. The fault protection is specified as current limiting, and control features include frequency control, soft start, and synchronization.
This controller is suitable for applications requiring efficient power conversion with precise control over switching intervals. Its design allows for independent programming of time delays for dead-time control at the turn-on of each output stage.
