DN85 ZXSC400 1W/3W buck LED drivers
In Figure 1, ZXSC400 is configured as a high efficiency buck LED driver. The target applications are either 1W (350mA) or 3W (700mA) drivers for white LED driven from a 4 cell battery, or a 2alkaline cell input for flashlights. The supply voltage for ZXSC400 reference design is: VIN = 3.8V to 6V.
Parts lists for 1W and 3W design are shown in Table 1 and Table 2 respectively. Performance data is measured based on two different LED's V-F binning with 0.3V V-F difference.
