Description
The MP2107 is an internally compensated 1.5MHz fixed-frequency PWM synchronous step-down regulator. MP2107 operates from a 2.7V to 5.5V input and generates an output voltage as low as 0.8V. The MP2107 integrates a 60mO high side switch and a 60mO synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, the MP2107 based solution delivers a very compact footprint with a minimum component count. The MP2107 is available in a small 3mm x 3mm 10-pin QFN package and the MP2107A is available in an 8-pin SOIC package with an exposed pad.

SWITCH NODE LAYOUT CONSIDERATIONS FOR EMCARTICLEThe switch node of a switching regulator or power converter circuit is a critical conduction path that requires special attention when designing the PCB layout. This circuit node is where one or more power semiconductor switches (such as a MOSFET or diode) connect to a magnetic energy-storing device (such as an inductor or transformer winding). The switching signals of this circuit node contain fa...

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 ...

ANALOG SIGNAL VS. DIGITAL SIGNALSARTICLEA signal is an electromagnetic or electrical current that carries data from one system or network to another. In electronics, a signal is often a time-varying voltage that is also an electromagnetic wave carrying information, though it can take on other forms, such as current. There are two main types of signals used in electronics: analog and digital signals. This article discusses the correspond...
