MP28200GG-P Monolithic Power Systems

MP28200 Ultra-Low 500nA I , High Efficiency, q Wide Input 2V-5.5V, 1.5MHz, 200mA, Step-Down Regulator The Future of Analog IC Technology DESCRIPTION FEATURES The MP28200 is a monolithic power- Ultra-Low I : 500nA q management unit containing 200mA, high- Wide 2.0V to 5.5V Operating Input Range efficiency, step-down, switching converters. The 7 Selectable Output Voltages nanoamp quiescent current provides extremely Up to 200mA Output Current high efficiency when the load current is down in 1.5MHz Switching Frequency in Continuous the A range. With minimum input voltage as Conduction Mode (CCM) low as 2V, the MP28200 allows the system to 100% Duty Cycle in Dropout operate directly from the battery. 0.25 and 0.25 Internal Power MOSFET Switches The constant-on-time control scheme provides fast transient response, high light-load Cycle-by-Cycle Over-Current Protection (OCP) efficiency, and requires minimal capacitance. The regulation can be made tight by integrating Short-Circuit Protection (SCP) with Hiccup an error amplifier to correct the output voltage. Mode Over-Temperature Protection (OTP) The CTRL pins control the on/off and output Available in a QFN-12 (2mmx2mm) voltage selection functions. Package Fault protection features include under-voltage APPLICATIONS lockout (UVLO), over-current protection (OCP), and thermal shutdown. Wearables IOT The MP28200 requires a minimal number of Portable Instruments readily available, standard, external components and is available in a small QFN-12 Battery-Powered Devices (2mmx2mm) package. All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For MPS green status, please visit the MPS website under Quality Assurance.
