Features
Key features include a fixed-frequency operation at 2.25 MHz, which minimizes interference with wireless transmissions, and an adjustable output voltage, typically ranging from 0.6V to the input voltage. The device offers an enable pin for easy power sequencing and a power-good signal for system monitoring. It also includes overcurrent protection, thermal shutdown, and short-circuit protection to enhance reliability.
With its compact 2mm x 2mm VSON package, the TPS62822DLCR is designed for space-constrained applications, such as smartphones, wearables, and portable electronics, offering a balance of performance, efficiency, and size.
Pinout
1. VIN: Input voltage supply pin. It is where the input voltage is applied.
2. SW: Switch pin. It connects to the inductor and aids in step-down conversion by switching.
3. GND: Ground pin. It serves as the return path for the input voltage.
4. FB: Feedback pin. It is used to set the output voltage by connecting it to the center of a resistor divider network from the output voltage to GND.
5. EN: Enable pin. This pin allows the converter to be turned on or off; connecting it high enables the device.
6. PG: Power Good pin. This pin indicates whether the output voltage is within a certain range, typically used for sequencing or fault detection.
