Detailed Pin Configuration

The TPS24700DGK features the following pin configuration:

1. EN (Enable): Controls the device's operation.
2. OV (Overvoltage): Monitors the input voltage level.
3. GND (Ground): Reference ground for the device.
4. FB (Feedback): Connects to an external resistor divider network to set the overvoltage threshold.
5. VOUT (Output Voltage): Provides regulated output voltage.
6. PG (Power Good): Indicates the status of the output voltage.
7. VIN (Input Voltage): Connects to the input power source.
8. NC (No Connection): Unused pin.

Functional Features

• Overvoltage Protection: Monitors the input voltage and shuts down the output when it exceeds a user-defined threshold.
• Adjustable Threshold: Allows users to set the overvoltage threshold according to their specific requirements.
• Fast Response Time: Quickly responds to overvoltage events, minimizing the risk of damage to downstream components.
• Power Good Indicator: Provides a signal indicating the status of the output voltage.

Advantages and Disadvantages

Advantages
