Consider a scenario where you need to design a power supply for a low-power sensor node powered by a single AA battery (nominally 1.5V). The sensor node requires a stable 3.3V supply. Using the LT1073 datasheet, you can determine the appropriate external components (inductor, capacitor, and resistor values) to configure the LT1073 in a boost configuration to efficiently convert the battery voltage to the required 3.3V. Here’s a simple table to represent the typical application parameters:
| Parameter | Value |
|---|---|
| Input Voltage | 0.8V - 6V |
| Output Voltage | Adjustable (up to 30V typically) |
| Switching Frequency | Varies with load, typically 25kHz |
With the information presented in the LT1073 datasheet, designers can choose external components that will determine:
- The proper external components for the LT1073, such as the inductor, capacitor, and resistors.
- Determine the components’ proper configurations, such as boost or buck configuration.
- Optimal operational voltages and current.
