AN703 Designing DC/DC Converters

Pre-Regulator A BiC/DMOS power integrated circuit process is used to integrate a high-voltage (120-V rated) lateral DMOS transistor with the CMOS PWM controller. By using an ion implant to shift the gate threshold to a negative value, as shown in Figure 1, the transistor is made to operate as a depl.

The distributed power approach is employed in telecom systems, large minicomputers, and in other applications where reliability is a primary concern. To illustrate some of the performance capabilities of this BiC/ DMOS switchmode controller IC, a 15-W forward converter design is presented. The converter provide.
