Package
The TLV62084DSGR is a step-down converter from Texas Instruments, and it is packaged in a 2 mm x 2 mm SON-8 (Small Outline No-lead) package, also known as the DSG package type. This package provides a compact and thermally efficient solution suitable for space-constrained applications.
Pinout
The TLV62084DSGR is a step-down converter from Texas Instruments, typically housed in a small 2 mm x 2 mm, 8-pin WSON (DSG) package. Here is a brief overview of its pin functions:
1. VIN (Pin 1): Input voltage supply pin. Connect to the input voltage source.
2. EN (Pin 2): Enable pin. A high level on this pin enables the device; a low level disables it.
3. PG (Pin 3): Power Good pin. This open-drain output indicates when the output voltage is within regulation.
4. FB (Pin 4): Feedback pin. Connect to the midpoint of a resistor divider to set the output voltage.
5. GND (Pin 5): Ground pin. Connect to the system ground.
6. SW (Pins 6 & 7): Switch node pins. These are the output switch pins, which connect to the inductor.
8. VOS (Pin 8): Output voltage sense pin. Connect directly to the output voltage.
These pins allow the TLV62084DSGR to efficiently convert a higher input voltage to a lower output voltage, typically used in power management applications.
