Biphase Current Mode Controller - Semtech Corporation

The SC2422A biphase, current mode controller is de- signed to work with Semtech smart synchronous drivers, such as the SC1205 SC1305 or the SC1405 to provide the DC/DC converter solution for the most demanding Micro-processor applications. Input current rather than output current sensing is used to guarantee precision phase to phase current matching using a single sense resistor on the input power line. Accurate current sharing and pulse by pulse current limit are implemented without the power loss and transient re- sponse degradation associated with output current sense methods. Two phase operation allows significant reduction in input/output ripple while enhancing tran- sient response. The DAC step size and range are programmable with external components thus allowing compliance with new and emerging VID ranges. A novel approach implements active droop, minimizing output capacitor requirements during load transients. This avoids the pitfalls of the passive droop implemen- tation. This feature also allows easy implementation of N+1 redundancy and current sharing among modules. By Semtech Corporation
