SC2446 controller equivalent, dual-phase single or two output synchronous step-down controller.
2-Phase synchronous continuous conduction mode
for high efficiency step-down converters Out of phase operation for low input current.
The SC2446 employs fixed frequency peak current-mode control for the ease of frequency compensation and fast transient .
The SC2446 is a high-frequency dual synchronous stepdown switching power supply controller. It provides outof-phase high-current output gate drives to all N-channel MOSFET power stages. The SC2446 operates in synchronous continuous-conduction mode. B.
