LT1307BIS8 升壓/降壓
轉換器的典型應用
電路。 LT1307B 是一款微功耗、固定頻率 DC/DC 轉換器,可在低至 1V 的輸入電壓下工作。業內率先通過單節
電池電源實現真正的
電流模式 PWM 性能。 LT1307B 在輕負載時不會切換到突發模式操作,從而以犧牲輕負載效率為代價消除低頻輸出紋波

Typical Application Circuit for LT1307BIS8 Step-Up/Step-Down Converter. The LT1307B is a micropower, fixed frequency DC/DC converter that operates from an input voltage as low as 1V. First in the industry to achieve true current mode PWM performance from a single cell supply. The LT1307B does not shift into Burst Mode operation at light loads, eliminating low frequency output ripple at the expense of light load efficiency
