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.

MEETING THE IMPEDANCE MASK: STRATEGIES FOR PDN DESIGN AND OPTIMIZATIONARTICLEIn telecommunication applications, target impedance serves as a crucial benchmark for PDN design. It ensures that the die operates within an acceptable level of rail voltage noise, even under the worst-case transient current scenarios, by defining the maximum allowable PDN impedance for the power rail on the die. This article will focus on the optimization techniques to meet the target impedance ...
