Title:
可変ピーク電流および可変オフ時間制御を有するスイッチドコンバータ
Document Type and Number:
Japanese Patent JP4874033
Kind Code:
B2
Abstract:
A converter coupled to a DC voltage input and connectable to a load, includes a signal responsive switch coupled between a first circuit point and a second circuit point. In lieu of burst mode operation during low load conditions, the peak switch current is varied directly with load condition and a switch deactivation interval is varied inversely with load condition. The switch deactivation level is within a maximum level to avoid audio frequency band interference, while maintaining high efficiency operation throughout the load range.
