Description
The MPQ4420 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution to achieve a 2A continuous output current with excellent load and line regulation over a wide input supply range. The MPQ4420 has synchronous mode operation for higher efficiency over the output current load range. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection and thermal shut down. The MPQ4420 requires a minimal number of readily-available standard external components, and is available in a space-saving 8-pin TSOT23 package.

WHEN IS IT BENEFICIAL TO PLACE A COPPER LAYER BENEATH DC/DC POWER SUPPLIES?ARTICLEEngineers often disagree on whether the inductive bottom of DC/DC power supplies should be laid with copper. The first argument is that laying copper under the inductor produces eddy currents on the ground plane. As a result, the eddy current affects the power inductor’s inductance and increases the system loss, and the ground plane noise impacts other high-speed signals. The second argument is th...

QUICK TIPS TO DIAGNOSE AND STABILIZE AN UNSTABLE SWITCHING POWER SUPPLYARTICLEAn unstable power supply can cause severe system issues, such as audible noise from the passive components, unexpected jittering in the switching frequency, extreme oscillations on the output voltage during load transient events, and failures in the semiconductor switches. While there are various reasons for instability, an un-tuned compensation network accounts for majority of instability issues ...
