GENERAL DESCRIPTION
Efficient, compact and dynamic power conversion is achieved using a novel, digitally controlled Pulse Width and Frequency Modulation (PWFM) like control concept, integrated low RdsON CMOS power switches with low parasitic capacitances, and fully synchronous rectification. Deadlock is prevented by an on-chip undervoltage lockout circuit.
