General Description
The SC2443 is a high-frequency dual synchronous step-down switching power supply controller.
It provides out-of-phase high-current output gate drives to all N-channel MOSFET power stages.
The SC2443 operates in synchronous continuous-conduction mode.
Key Features
- u Wide input voltage range: 4.7V to 16V u 0.5V feedback voltage for low-voltage outputs u Programmable frequency up to 1 MHz per phase u 2-Phase synchronous continuous conduction mode for high efficiency step-down converters u Out-of-phase operation for low input current ripples u Output source and sink currents u Fixed frequency peak current-mode control u 75mV/-110mV maximum current sense voltage u Inductor DCR current-sensing for low-cost.
