The TEA1755T/1,518 from NXP Semiconductors is a highly integrated Switched Mode Power Supply (SMPS) controller IC. It combines controllers for Power Factor Correction (PFC) and a flyback converter, enabling cost-effective power supply designs with a minimal number of external components.
This device operates with a universal mains supply between 70V (AC) to 276V (AC) and supports a voltage range of 13.4V to 38V, delivering up to 250W of power. The PFC operates in Quasi-Resonant (QR) or Discontinuous Conduction Mode (DCM) with valley switching. The flyback controller also operates in QR or DCM at high power levels, switching to Frequency Reduction (FR) mode at medium power levels and burst mode at very low power levels to maintain high efficiency.
Key green features include an on-chip start-up current source, reduced IC supply current during burst mode, and power-down functionality for low standby power. The TEA1755T/1,518 is housed in a 16-SOIC package and is designed for surface mounting.
Its operating temperature range is -40°C to 155°C (TJ), and it includes fault protection for current limiting, overload, over-power, over-temperature, and over-voltage conditions. The isolated output and integrated switch further simplify design.
