Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 2.7V to 5.5V to avoid damage to the device.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted from 0.6V to 5.25V using external resistors. Refer to the datasheet for specific resistor values.

3. Switching Frequency (FSW):

   • The LTC3534EGN operates at a fixed switching frequency of 1MHz, which helps in minimizing the size of external components.

4. Quiescent Current (IQ):

   • The quiescent current is typically 45μA when no load is present, making it suitable for low-power applications.

5. Efficiency (η):

   • For optimal efficiency, operate within recommended conditions. At VIN = 3.3V, VOUT = 1.8V, and IOUT = 500mA, efficiency can reach up to 90%.

6. Shutdown Current (ISD):

   • When the shutdown pin is activated, the shutdown current drops to approximately 1μA, reducing power consumption.

7. Output Current Limit (ILIM):

   • The device has an internal current limit set to approximately 1.2A to protect against overcurrent conditions.

Note: Always refer to the manufacturer’s datasheet for detailed specifications and application notes.
