The Texas Instruments UC2879DWG4 is an enhanced bipolar phase-shifted full-bridge controller. It is designed to control a bridge power stage by phase shifting the switching of one half-bridge with respect to the other, enabling constant frequency pulse width modulation combined with resonant zero-voltage switching for high efficiency.
This device 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 10-MHz error amplifier, pin-programmable undervoltage lockout, and a low startup current of 150 μA. It also incorporates soft-start control and outputs that are active low during UVLO.
The UC2879DWG4 is suitable for applications requiring efficient power conversion. It is available in a 20-SOIC package and supports surface mount installation. The operating temperature range is -40°C to 85°C (TA).
This controller provides essential fault protection, including current limiting, and features for frequency control, soft start, and synchronization.
