IP명 DC-DC Converter With On-Chip Current-Sensing and Digital AMP
Category Analog Application PMIC
실설계면적 4㎛ X 4㎛ 공급 전압 1.2V
IP유형 Hard IP 동작속도 2MHHz
검증단계 Simulation 참여공정 SS65-1902
IP개요 This IP is a CMOS VCO(Voltage Controlled Oscillator) based PWM DC DC Buck converter utilizing voltage sensing signals to determine the duty cycle ratio and increase the power efficiency. The proposed circuit employs VCOs to control digital circuit and duty cycle modulator. This circuit receives the input voltage of 2.7 ~ 3.3V and generates the output voltage of 1V ~ 1.5V with the load current of 1mA to 500mA and switching frequency of 2MHz. The maximum power conversion efficiency of the chip is simulated to be 95%
