Abstract
- A new monolithic fast-response buck converter using spike-reduction current-sensing circuits is proposed in this paper. The proposed converters are designed and implemented with TSMC 0.35-mum DPQM CMOS processes. The operation frequency can be up to 1.887 MHz. The response time is only 2 mus and compared with other references. The maximum output current is 750 mA, and the maximum power efficiency can be up to 89.1% at 2.442-W output power. The chip area is only 2.157 mm2.
