The LTC3704EMS is a high-performance DC/DC step-up controller. It is typically housed in a 10-lead MSOP (Mini Small Outline Package), meaning it has 10 pins. Here is a brief overview of its key functions:
1. VIN (Pin 1): This pin is the input supply voltage for the internal circuitry.
2. SW (Pin 2): The switch pin that drives the gate of the external N-channel MOSFET.
3. SENSE– (Pin 3) and SENSE+ (Pin 4): These pins are used for current sensing across an external sense resistor.
4. GND (Pin 5): Ground pin for the device.
5. TG (Pin 6): This is the top gate drive pin that connects to the gate of the high-side MOSFET.
6. BG (Pin 7): Bottom gate drive pin for the low-side MOSFET.
7. VFB (Pin 8): Feedback voltage pin for regulating output voltage.
8. SHDN/RT (Pin 9): Shutdown and frequency select pin.
9. SS (Pin 10): The soft-start pin to control startup inrush current.
These functions collectively support the controller’s operation, enabling efficient step-up voltage conversion.
