Features
Key features of the PAM2861CBR include its high-efficiency performance, often exceeding 90%, thanks to its synchronous rectification architecture. It also offers low quiescent current, which is beneficial for extending battery life in portable devices. The device typically integrates protection features such as over-current, over-temperature, and short-circuit protection to ensure safe operation.
The PAM2861CBR is housed in a compact package suitable for space-constrained applications and supports features like automatic PWM/PFM mode switching to optimize efficiency across different load conditions. Its fast transient response and low output ripple make it ideal for powering sensitive electronics that require stable voltage supply.
Pinout
1. SW (Switch): Connects the inductor to switch the power.
2. GND (Ground): Ground reference for the device.
3. FB (Feedback): Used to set the output voltage through a resistor divider network.
4. EN (Enable): Enables or disables the device. When high, the device is operational.
5. VIN (Input Voltage): Supplies the input voltage to the device.
6. NC (No Connect/Not internally connected): Some configurations might leave one pin not internally connected, but it is generally recommended to check the specific datasheet.
This configuration allows the PAM2861CBR to efficiently convert a higher input voltage to a lower output voltage, suitable for various portable and low-power applications. Always refer to the specific datasheet for detailed information about electrical characteristics and application guidelines.
