Package
The TPS54331D is a step-down DC-DC converter from Texas Instruments, provided in an 8-pin SOIC (Small Outline Integrated Circuit) package with PowerPAD. This package type allows for efficient thermal performance and compact size ideal for surface mounting on printed circuit boards.
Pinout
The TPS54331D is a 3-A, 28-V step-down voltage regulator from Texas Instruments. It typically comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Here is a brief description of each pin function:
1. BOOT (Pin 1): Supplies a bootstrap voltage for the high-side MOSFET driver. A bootstrap capacitor is connected between this pin and the SW pin.
2. VIN (Pin 2): Input voltage supply pin for the device. Connect this to the input voltage source.
3. EN (Pin 3): Enable pin. Used to enable or disable the device. A high level enables the device, while a low level disables it.
4. SS/TR (Pin 4): Soft-start/tracking pin. Connect a capacitor to this pin to set the soft-start timing.
5. COMP (Pin 5): Compensation pin. Used for external compensation of the control loop.
6. GND (Pin 6): Ground pin. The ground reference for the device.
7. VSENSE (Pin 7): Feedback voltage sense pin. Connect this to the output voltage to regulate the desired output.
8. SW (Pin 8): Switch node pin. Connect this to the inductor and bootstrap capacitor.
This configuration is designed to provide efficient power conversion in a compact form factor suitable for a range of applications.
