But limited by time and my experience, there are still some insufficiency. Such as, reduce the quiescent current and combine PFM mode with PWM mode to improve the efficiency.
由于研究时间和本人经验水平所限，本设计中还有许多不足之处需要做进一步的研究和改进。
It operates both in current mode at high output load and in pulse frequency modulation (PFM) at light load to reduce the power dissipation.
它在重载下工作于电流控制模式，轻载下工作于脉冲频率调制(PF M)模式来降低功耗。
