... The following design discussions are limited to step-up, with a complete circuit shown in the Application Circuits section. The output voltage of the MAX5027/MAX5028 is fixed at 30V. The output voltage of the MAX5025/MAX5026 is set by two external resistors (R1 and R2, Figure 2 and Figure 3). First select the value the 5kΩ to PWM Controller 50kΩ ...
