High-Efficiency 4 Phase Synchronous Boost Conv for Automotive Trunk Amplifier App Reference Design (PMP7969)

PMP7969 is a very high efficiency 4 phase boost controller synchronizable to external clock. Light load efficiency is excellent due to phase shedding capability. Synchronous rectifier also improves efficiency. High effective switching frequency obtained with multiphase over single phase, and current sharing accuracy of ±10%. Bypass mode capable when Vin > Vout.
