The MP28200 is a monolithic power management unit containing 200mA high efficiency step-down switching. The sub microampere quiescent current provides extremely high efficiency when load current is low down to uA range. With the input range up to 5.5V, the MP28200 is ideal for powering battery-powered devices.
The constant-on-time control scheme provides fast transient response, high light load efficiency as well as the minimum capacitors.
The regulation is tight by integrating an error amplifier to correct the output voltage.
The CTRL pins control the ON/OFF and output voltage selection function.
Fault condition protection includes UVLO, over current protection, and thermal shutdown.
The MP28200 requires a minimum number of readily available standard external components and is available in a small QFN12 (2x2mm) package.
