IP명 Design of buck converter for the portable device application
Category Analog Application DC-DC Converter
실설계면적 3.8㎛ X 1.9㎛ 공급 전압 3.3V
IP유형 Hard IP 동작속도 1MHz
검증단계 Silicon 참여공정 MS180-1902
IP개요 In the power constraint devices, power efficiency is a
one of the important topics. And for improving the power efficiency
of the DC-DC convertor, we can achieve high power efficiency of
the portable devices. So here we propose buck converter, in which
improved power efficiency. It consists of input block which
including switch MOS, output block which including inductor and
capacitor, and control block which including block groups for
generating PWM signal. The simulation result of this circuit showed
1.788 V of output voltage, 3.799 mV of ripple voltage, and 97.259%
of power efficiency under the 3 V of power supplying condition in
the Cadence tool. And MagnaChip 180 nm process was used for
fabrication of the circuit.
