MPL
The EVBL2166-D-00A is an evaluation board designed to demonstrate the capabilities of the MP2166 and MPQ2166,and is optimized for MPS's MPL-AY4020 series of power inductors. The MP2166 and MPQ2166 are dual PWM step-down regulators with internal compensation. The devices operate from a 2.7V to 6V input voltage (VIN) range, and can generate an output voltage (VOUT) as low as 0.6V. The MP2166 and MPQ2166 can be configured for a 2A/2A or 3A/1A output current (IOUT), and their low 60μA quiescent current (IQ) makes them ideal for portable equipment that runs on a single-cell lithium-ion battery.
The devices integrate dual, 55mΩ high-side MOSFETs (HS-FETs) and 20mΩ synchronous rectifiers (SRs) for high efficiency without an external Schottky diode. The MP2166 and MPQ2166 have peak current mode control as well as internal compensation, and are capable of low-dropout configurations. Both channels can operate at 100% duty cycle.
Full protection features include cycle-by-cycle current limiting and thermal shutdown. The MP2166 and MPQ2166 are available in QFN-18 (2mmx3mm) or QFN-18 (2.5mmx3.5mm) packages.

SWITCH NODE LAYOUT CONSIDERATIONS FOR EMCThe 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 SUPPLYAn 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 ...

USING EXTERNAL KNOBS TO IMPROVE TRANSIENT PERFORMANCE OF BUCK REGULATORS WITH AN INTEGRATED COMPENSATION NETWORKThe high power density requirement and board-level space constraints in modern applications — such as lighting, ADAS, and USB — call for higher integration in buck regulators. There is a trend to integrate MOSFETs and compensation networks inside the chip. This integration of the compensation network’s passive components saves cost, board space, and design iterations. However, it...
