Description
The MP28210 is a monolithic power management unit containing a 1A, high efficiency, step-down, switching converter. The nA quiescent current provides extremely high efficiency when the load current is within the μA range. With a minimum input voltage as low as 2V, the MP28210 allows the system to operate directly from the battery.
The constant-on-time (COT) control scheme provides fast transient response, high light-load efficiency, and requires minimal capacitance. The regulation can be made tight by integring an error amplifier to correct the output voltage.
The CTRL pins control the on/off and output voltage selection functions.
Fault protection features include under-voltage lockout (UVLO), over-current protection (OCP), and thermal shutdown.
The MP28210 requires a minimal number of readily available, standard external components, and is available in a small CSP-12 (1.2mmx1.6mm) package.
