摘要

An inductor switching hysteretic control boost DC-DC regulator is presented in this paper with a newly proposed current-sensing technique named "Emulated-Ramp Feedback, ERF". A boost regulator with a chip verification which achieves a simple structure and low cost is presented for LED driving applications. The regulator was fabricated in a TSMC 0.25μm high voltage (HV) CMOS process with a specification of 5V to 12V in a 0-300mA load range. And a peak efficiency of 92.1% is achieved with only 1.014mm2 chip area.
