Descripción
- DN06074/D, 65W Off-Line Adapter Design Note operates in both CCM (continuous conduction mode) and DCM (discontinuous conduction mode), allowing it to accept a wide universal input voltage range. The CCM operation provides desired full load performance with good efficiency and low ripple of primary current. The DCM operation permits an increase of efficiency under the light load conditions, by decreasing the switching losses. The device switches at 65 kHz which represents a good trade-off between switching losses and magnetics size. For meeting the design requirements, the NCP1236 fixed frequency controller was selected. The design of this notebook adapter is focused to obtain the maximum efficiency and lowest no load input power. The adapter consists of several important sections
