MP28200 - Step-Down Regulator

General Description

The MP28200 is a monolithic powermanagement unit containing 200mA, highefficiency, step-down, switching converters.

The nanoamp quiescent current provides extremely high efficiency when the load current is down in the µA range.

Key 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.

The Future of Analog IC Technology DESCRIPTION The MP28200 is a monolithic powermanagement unit containing 200mA, highefficiency, 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.
