MaxLinear SP6153

Description

The SP6153ER is designed with a very accurate 1.0% reference over line, load and temperature. Figure 1 & 2 data show a typical SP6153 evaluation board efficiency and regulation plots, with efficiencies up to 93% and output currents up to 20A. The output voltage ripple of less than 50mV at full load and the LX node are shown in figure 3. Figures 4 and 5 illustrate a 10A to 20A and 1A to 20A Load Step. Short circuit and current limit are shown in Figures 6 and 7. Typical startup characteristics into a full load and no load are shown in figure 8 and 9. All data was taken at 5Vin and 1.8VoutWhile data on individual power supply boards may vary, the capability of the SP6153ER of achieving a high accuracy over a range of load conditions shown here is quite impressive and desirable for accurate power supply design.
