The A8281SLB output is set to 13 or 18-V by the VSEL terminal. It is supplied in a 16-lead SOIC power-tab package. The power tabs are at ground potential and need no electrical isolation. The A8282SLB output is set to 12, 13, 18, or 20-V by the VSEL terminals. Additionally, it is possible to increase the selected voltage by 1-V to compensate for the voltage drop in the coaxial cable (LLC terminal high). It is supplied in a 24-lead SOIC power-tab package. The power tabs are at ground potential and need no electrical isolation. The A8282SLB is an improved version of the A8283SLB, without a bypass switch.
