说明

  • Typical Application for LD39020 200 mA very low quiescent current linear regulator IC. STLD40D is a boost converter that operates from 3.0 V to 5.5 V. It can provide an output voltage as high as 37 V and can drive up to 10 white LEDs in series. The converter is a PFM (pulse frequency modulation) inductor switch that can work in discontinuous (DCM) mode operation. A minimum OFF time of the embedded boost switch TSW is fixed internally and allows limiting the switching frequency

主要特色

  • Conversion Type
    DC to DC
  • Topology
    LDO
