Package
The TPS562202DRLR is a DC-DC buck converter from Texas Instruments. It comes in an SOT-563 package type, which is a small, surface-mount package ideal for space-constrained applications. The package code "DRL" refers to this specific format, which typically contains 6 pins.
Pinout
The TPS562202DRLR is a DC-DC buck converter from Texas Instruments. It comes in a 6-pin SOT-563 package. Here is a brief description of its pin functions:
1. VIN: Input voltage pin. Connects to the input power source.
2. GND: Ground pin. Common ground for the device and should be connected to the system ground.
3. SW: Switch node pin. Connects to the output inductor to facilitate the step-down voltage conversion.
4. EN: Enable pin. Used to enable or disable the device. A high level on this pin enables the device.
5. FB: Feedback pin. Connects to a resistor divider from the output to adjust the output voltage.
6. SS/TR: Soft start/tracking pin. Used to control the soft start period to limit inrush current or to track the voltage of another supply.
These pins facilitate the primary function of the TPS562202DRLR, which is to efficiently convert a higher input voltage to a lower output voltage suitable for powering electronic circuits.
