The Future of Analog IC Technology
DESCRIPTION
The MP28200 is a monolithic power-
management unit containing 200mA, high-
efficiency, step-down, switching converters. The
nanoamp quiescent current provides extremely
high efficiency when the load current is down in
the µA range. With minimum input voltage as
low as 2V, the MP28200 allows the system to
operate directly from the battery.
The constant-on-time control scheme provides
fast transient response, high light-load
efficiency, and requires minimal capacitance.
The regulation can be made tight by integrating
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 MP28200 requires a minimal number of
readily available, standard, external
components and is available in a small QFN-12
(2mmx2mm) package.
