Instructions for Use:
Circuit Design:
- Ensure the input voltage is within the specified range (4.5V to 28V).
- Use appropriate external components such as inductors, capacitors, and resistors to set the output voltage and stabilize the circuit.
- Place the output capacitor close to the device to minimize noise and improve stability.
Output Voltage Setting:
- The output voltage can be adjusted using a resistor divider network connected to the feedback pin (FB).
- The formula to calculate the output voltage is ( V_ = V_ times left(1 + fracright) ), where ( V_ ) is typically 0.8V.
Thermal Management:
- Ensure adequate heat dissipation, especially when operating at high output currents.
- Use a heatsink or PCB copper area to help dissipate heat if necessary.
Enable Pin:
- The enable pin (EN) can be used to control the on/off state of the regulator.
- Applying a high signal (typically >1.2V) to the EN pin turns the regulator on.
- A low signal (<0.4V) will turn the regulator off, entering a low-power shutdown mode.
Protection Features:
- The device includes overcurrent, overvoltage, and thermal shutdown protection.
- These features help prevent damage to the device under fault conditions.
Layout Considerations:
- Keep the power traces short and wide to reduce resistance and inductance.
- Use ground planes to provide a low-impedance path for return currents.
- Place decoupling capacitors close to the input and output pins to filter noise.
Storage and Handling:
- Store the device in a dry, cool environment to avoid moisture damage.
- Handle the device with care to avoid static discharge, which can damage sensitive components.
