The LT3465ES6 is a micropower step-up DC/DC converter with an integrated Schottky diode, designed by Analog Devices. It is housed in a 6-pin SOT-23 package. Below is a concise breakdown of its pin configuration and functions:
1. SW (Pin 1): This is the switch pin, which connects to the inductor and the internal power switch.
2. GND (Pin 2): This pin is connected to the ground.
3. FB (Pin 3): The feedback pin is used to set the output voltage through an external resistor divider.
4. SHDN (Pin 4): The shutdown pin turns the device on or off. Pulling this pin low shuts down the converter, reducing the supply current to less than 1µA.
5. VIN (Pin 5): This is the input voltage pin, where the supply voltage is applied.
6. VOUT (Pin 6): The output voltage pin delivers the regulated voltage.
The LT3465ES6 is typically used in applications requiring efficient DC/DC conversion, offering low quiescent current and high efficiency.
