PAM2301CAAB120

PAM2301CAAB120 is a low-noise, synchronous buck DC/DC clocked switching regulator which offers adjustable output voltage and provides two independent regulation loops. It is categorized under PMIC (Power Management Integrated Circuits) Voltage Regulators-DC DC Switching Regulators. The PAM2301CAAB120 application field involves aspects of automotive power management, battery management (especially in electric vehicles) or any high efficiency LED lighting systems.

In total, the PAM2301CAAB120 offers multiple control and protection-fuse modes for a wide range of applications. To come to the functionality and working principles of the device, PAM2301CAAB120 integrates four integrated power switches to form a synchronous buck converter, enabling 4A and 5A continuous current . Moreover, it has a programmable frequency up to 2MHz (7pin). To provide a dynamic response, PAM2301CAAB120 comes with a dynamic/predictive switching mode (3pin).

In more granular terms, PAM2301CAAB120 integrated four power switches to form a synchronous buck converter, including two switches that form the main switch pair, one switch dedicated to power stage, and one switch dedicated to signal. Specifically, the two switches of the main switch pair work together to switch and control the inductor current in both directions to provide a highly efficient power conversion. On the other hand, the power stage switch controls when the inductor current is short-circuited to ground to reset the inductor current when the current reaches its peak value. Lastly, the signal pin controls when the two switches of the main switch pair are disconnected from the circuit to reset the inductor current before the current reaches its peak value.

In addition, PAM2301CAAB120 also offers a constant current mode for lighting applications, by allowing for soft-start and surge current protection. By programming the loop gain of the device, the control loop can be configured to operate in either current mode or voltage mode for adjustable output voltage between 0.6V and 5V. As for the protection modes afforded by PAM2301CAAB120, the device offers a comprehensive set of protective features that include over voltage protection (OVP), undervoltage protection (UVP), over current protection (OCP), open loop protection (OLP), and overtemperature shut down (TSD).

To conclude, PAM2301CAAB120 is a low-noise, synchronous buck DC/DC clocked switching regulator which offers adjustable output voltage and protections. It has four integrated power switches to form a synchronous buck converter, enabling 4A and 5A continuous current, and a programmable frequency of up to 2MHz (7pin). It also provides a dynamic/predictive switching mode, as well as soft-start, surge current protection and overtemperature shut down. With all of these features in mind, PAM2301CAAB120 is an excellent choice for the automotive power management, battery management (especially in electric vehicles) and LED lighting systems.
