NXP Semiconductors TEA2376xT

The TEA2376xT family of IC’s is the latest NXP digital configurable two-phase interleaved Power Factor Correction (PFC) Controllers for high-efficiency power supplies. This PFC operates in discontinuous conduction mode or quasi-resonant mode with valley switching to optimize efficiency. The TEA2376 enables the building of an interleaved power factor supply, which is easy to design with a low external component count. For low-load operation with good efficiency, phase shedding and burst mode operation are included.

Key features

• High efficiency at low loads with numerous protections
• High configurability via MTP programming - QR/DCM with valley switching
• Low external BOM count - Good interleaving performance
• Best PF/THD with phase shift - Programable burst and phase shedding transitions

Additional features

• Programmable phase shedding and burst mode operation
• The Power Factor Correction (PFC) operates in discontinuous conduction mode or quasi-resonant mode with valley switching to  optimize efficiency. Dual output over voltage and Inrush current protections
• High power factor (PF) and low total harmonic distortion (THD), also at high input voltages
• Many parameters can be configured during evaluation by an easy programmable user interface
• Good phase control over full input voltage range and low audible noise
• Power good output and a burst mode input pin (TEA2376DT)
• Live monitoring of (internal) IC status values over time with the help of the user-friendly GUI like oscilloscope reading
• I²C communication while in operation
• Valley/zero voltage switching for minimum switching losses
• High efficiency from high load to medium load and low load by phase shedding and burst mode operation
• NXP^® GreenChip Technology
• Protections can independently be set to latched, safe restart, or latched after several attempts to restart
• Dual output overvoltage protection (OVP)
• Supply undervoltage protection (UVP) and overvoltage protection (OVP)
• Internal and external overtemperature protection (OTP)
• Overcurrent protection (OCP)
• Inrush current protection (ICP)
• Brown-in/brown-out protection
