The SC2446A is a high-frequency dual synchronous stepdown switching power supply controller. It provides outof-phase output gate signals. The SC2446A operates in synchronous continuous-conduction mode. Both phases are capable of maintaining regulation with sourcing or sinking load currents, making t.
2-Phase synchronous continuous conduction mode for high efficiency step-down converters Out of phase operation for low input current ripples Output source and sink currents Fixed frequency peak current-mode control 50mV/-75mV maximum current sense voltage Inductive current-sensing for low-cost applications Optional resistor current-sensing for precise current-limit Dual outputs or 2-phase single output operation Excellent current sharing between individual phases Wide input voltage range: 4.7V to 16V Individual soft-start, overload shutdown and enable Duty c.
