Description
The MP2141Q is a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs. The MP2141Q achieves 1.5A of continuous output currents from a 2.3V to 5.5V input voltage with excellent load and line regulation.
The constant-on-time (COT) control scheme provides fast transient response and eases loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown.
The MP2141Q is ideal for a wide range of applications including high performance DSPs, wireless power, portable and mobile devices, and other low-power systems.
The MP2141Q requires a minimal number of readily available, standard, external components and is available in an ultra-small SOT563 package.

ARTICLE
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 ...
