Description
The MP21600 is a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs. The MP21600 achieves 0.6A of continuous output current from a 2.3V to 5.5V input voltage range with excellent load and line regulation. The output voltage can be regulated as low as 0.6V.
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 MP21600 is ideal for a wide range of applications, including high-performance DSPs, wireless power, portable and mobile devices, and other low-power systems.
The MP21600 requires a minimal number of readily available, standard, external components is available in an ultra-small QFN-6 (1.0mmx1.5mm) package.

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...
