The LT3469ETS8 is a high-voltage micropower inductorless charge pump DC/DC converter with an integrated Schottky diode, designed by Analog Devices (formerly Linear Technology). It typically comes in an 8-pin TSOT-23 package. Here is a brief overview of its pin functions:
1. VIN (Pin 1): Input voltage supply pin.
2. GND (Pin 2): Ground pin.
3. SHDN (Pin 3): Shutdown control pin. Pulling this pin low disables the device, reducing the quiescent current.
4. CAP+ (Pin 4): Positive connection for the flying capacitor.
5. CAP- (Pin 5): Negative connection for the flying capacitor.
6. VOUT (Pin 6): Output voltage pin.
7. CPOUT (Pin 7): Charge pump output pin.
8. FB (Pin 8): Feedback pin for setting the output voltage through an external resistor network.
This device is primarily used for generating a negative voltage from a positive supply, often used in biasing applications for LCD displays or other small-signal devices.
