TEA18362T SMPS Controller IC

NXP Semiconductors TEA18362T GreenChip SMPS controller IC is intended for flyback power supplies that can deliver up to 75W. At high power levels, NXP TEA18362T operates in quasi-resonant (QR) mode. At lower power levels, the controller switches to frequency reduction (FR) or discontinuous conduction mode (DCM) and limits the peak current to ~25% of the peak current. At low power levels, when the switching frequency drops below 25kHz, the flyback converter switches to burst mode. This feature ensures high efficiency at low power and excellent no-load power performance.
