N80387X-OLD Datasheet
N80387X-OLD Price Switching regulator chips are available from compa- nies such as Linear Technology, Maxim, Micro Linear, and Motorola, among others. The driver lC typically in- cludes the low-on-resistance boost-current FET device on-chip, to minimize cost and complexity. However, such solutions still require a passive magnetic compo- nent (a transformer or inductor), and bulk current sup- ply capacitor. N80387X-OLD on stock
The step-down case (Figure 5) differs from the step-up in that the inductor current flows through the load during both the charge and discharge periods of the inductor. Current through the switch should be limited to ~650mA in this mode. Higher current can be obtained by using an external switch (see Figure 6). The ILIM pin is the key to successful operation over varying inputs. |
