System and method to detect synchronous switching regulator light load |
摘要 |
An efficient and practical system and method to determine when a switching DC-DC regulator is under a light load condition. The light load condition is determined by monitoring the switch node voltage to detect a zero-crossing voltage that is load dependent and occurs when the average output current minus half the switching current at the switch node is less than or equal to zero.
