MP8130DJ-LF-P

MP28200 The Future of Analog IC Technology Ultra-Low 500nA Iq, High Efficiency, Wide Input 2V-5.5V, 1.5MHz, 200mA, Step-Down Regulator DESCRIPTION FEATURES 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.     Ultra-Low Iq: 500nA Wide 2.0V to 5.5V Operating Input Range 7 Selectable Output Voltages Up to 200mA Output Current 1.5MHz Switching Frequency in Continuous Conduction Mode (CCM) 100% Duty Cycle in Dropout 0.25Ω and 0.25Ω Internal Power MOSFET Switches Cycle-by-Cycle Over-Current Protection (OCP) Short-Circuit Protection (SCP) with Hiccup Mode Over-Temperature Protection (OTP) Available in a QFN-12 (2mmx2mm) Package 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. APPLICATIONS The MP28200 requires a minimal number of readily available, standard, external components and is available in a small QFN-12 (2mmx2mm) package.     Wearables IOT Portable Instruments Battery-Powered Devices All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
