MP2153
DESCRIPTION
The MP2153 is a monolithic, step-down, switchmode converter with built-in, internal power MOSFETs. The MP2153 achieves 3A of continuous output current from a 2.5V 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-bycycle current limiting and thermal shutdown.
The MP2153 is ideal for a wide range of applications, including solid-state drives, portable devices, and other low-power, lowvoltage systems.
The MP2153 requires a minimal number of readily available, standard, external ponents and is available in ultra-small SOT563 (1.6mmx1.6mm) or UTQFN-6 (1.2mmx1.6mm) packages.
