1 Design Example

Figure 1-1 Typical Application

This design example produces a variable load voltage boost. Applications such as Class H audio amplifiers, and LED drivers require a variable output voltage from a boost regulator to greatly improve the system efficiency. The load voltage range for this design is 24 V to 33 V and provides a maximum power of 200 W from a standard 12 V automotive battery. The output voltage is adjusted using the TRK pin of the device. The detailed parameters are presented in Table 1-1 and the component selection is discussed in Section 2.
