Pinout
The LT1930ES5#PBF is a high-efficiency, step-up DC/DC converter designed by Analog Devices (formerly by Linear Technology). It comes in a 5-lead SOT-23 package. Here is a brief description of its pin count and functions:
1. Pin 1 - SW (Switch): This is the power switch pin. It connects to the inductor and the output diode.
2. Pin 2 - GND (Ground): This is the ground reference for the device and must be connected to the system ground.
3. Pin 3 - FB (Feedback): This pin receives the feedback voltage from the external voltage divider connected to the output. It regulates the output voltage by comparing it with the internal reference.
4. Pin 4 - SHDN (Shutdown): This pin is used to shut down the converter to reduce power consumption. Pulling it low shuts down the device.
5. Pin 5 - VIN (Input Voltage): This is the input supply pin for the device. It supplies power to the internal circuitry and should be connected to the input voltage source.
This configuration makes the LT1930ES5#PBF suitable for small, high-efficiency applications.
