Firstly, an improved compensation scheme is introduced through the analysis and derivation of the traditional voltage-mode COT controlled buck converter model. Then, according to the application requirements of the design, Simplis software modeling is used to verify the correctness of the theoretical analysis. The 0.13[Formula: see text][Formula: see text]m BCD technology is used to tape out the DC\u2013DC converter of the improved voltage mode COT. The input voltage is 3.7\u20135.5[Formula: see text]V and the output voltage is 3.3[Formula: see text]V. The chip test mainly includes heavy-load condition in CCM operation, light-load condition in DCM operation, and load transient response. The test results show that the chip can remain stable under heavy-load and light-load conditions. The overshoot and undershoot in transient response can be quickly restored to steady state during the recovery process. Finally, compared with chips of the same type, it shows that the DC\u2013DC chip for portable electronic equipment designed in this paper adopts an internal compensation structure, which has good stability, simple design, small main chip area, simple peripheral equipment, and good application value. <\/jats:p>","DOI":"10.1142\/s0218126623500639","type":"journal-article","created":{"date-parts":[[2022,8,24]],"date-time":"2022-08-24T08:52:09Z","timestamp":1661331129000},"source":"Crossref","is-referenced-by-count":0,"title":["Design of DC\u2013DC Buck Converter Based on Improved Voltage-Mode COT Control"],"prefix":"10.1142","volume":"32","author":[{"given":"Peirong","family":"Huang","sequence":"first","affiliation":[{"name":"School of Microelectronics, Southeast University, No. 35, Jinxiang River Road, Nanjing, P.\u00a0R.\u00a0China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6099-1833","authenticated-orcid":false,"given":"Changyuan","family":"Chang","sequence":"additional","affiliation":[{"name":"School of Microelectronics, Southeast University, No. 35, Jinxiang River Road, Nanjing, P.\u00a0R.\u00a0China"}]}],"member":"219","published-online":{"date-parts":[[2022,9,28]]},"reference":[{"key":"S0218126623500639BIB001","doi-asserted-by":"crossref","first-page":"4301","DOI":"10.1109\/TPEL.2012.2191799","volume":"27","author":"Lin Y.
