Design of anti-jamming current-sensing circuit for current-mode buck regulator
摘要
Abstract
A novel anti-jamming integrated CMOS current-sensing circuit for current-mode buck regulators is presented.Based on the widely-used traditional current-sensing structure,anti-jamming performance is improved significantly by adding on-chip capacitors and one-shot circuit.Also the transient response is faster through the introduction of current offset.The circuit iS concise,simple to implement and suits for SoC applications with single power supply.A dual-output current-mode DC-DC buck converter with proposed structure has been fabricated with a 0.5μm CMOS process for validation.In the 2.5-5.5 V input range,the two channels work steadily in the load current range of 0-600 mA.And the measured maximum efficiency is up to 96%.关键词
