MP28210 - 1A Step-Down Regulator

General Description

The MP28210 is a monolithic power management unit containing a 1A, highefficiency, step-down, switching converter.

The nA quiescent current provides extremely high efficiency when the load current is within the µA range.

Key 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.

MP28210 Ultra-Low 500nA IQ, Wide Input 2V to 5.5V, 1A Step-Down Regulator with 1.2mmx1.6mm CSP Package DESCRIPTION The MP28210 is a monolithic power management unit containing a 1A, highefficiency, 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 integrating an error amplifier to correct the output voltage. The CTRL pins control the on/off and output voltage selection functions.
