A Compact One-Pin Mode Transition Circuit for Clock Synchronization in Current Mode Controlled Switching Regulators
A Compact One-Pin Mode Transition Circuit for Clock Synchronization in CurrentMode- Controlled Switching Regulators Abstract This paper describes a one-pin mode transition circuit that addresses the issues related to clocksynchronization in switching regulators during the mode transitions between external timing resistor and external clock. The proposed circuit reduces the circuit complexity needed to achieve mode transitionduring synchronization by utilizing switched-capacitor and sampling design techniques. It linearly converts the input clock frequency to a current to maintain constant amount of slope […]
