摘要

提出了一种新颖、简单的低功耗DC-DC概念。提出了一种在断续导通模式(DCM)下的预测峰值电流模式控制器。该设计能够在最小输出电容仅为27nF的情况下工作。测量表明，即使在最大负载电流步长下，纹波电压也很低，并且在良好的Vout直流控制下具有优异的瞬态响应。

An ultra-low power, 2mA Iout buck converter optimized for <50mV ripple at a load cap of only 27nF

A novel, simple DC-DC concept for low-power applications is presented. We propose a predictive peak-current mode controller in discontinuous conduction mode (DCM). The design is able to operate with a minimized output capacitor of only 27nF. Measurements shows low ripple voltage even at maximum load current steps and excellent transient response at a good DC control of Vout.
