MP28301GG-P Monolithic Power Systems

MP28301 Ultra-Low 500nA I , Wide Input 2-5.5V, Q 700mA Step-Down Regulator Plus 300nAI , Q 2-5.5V Input, 100mA LDO in a 2x2mm QFN The Future of Analog IC Technology DESCRIPTION FEATURES The MP28301 is a monolithic power- 700mA Buck Switcher management unit containing a 700mA, high- o Ultra-Low I : 500nA Q efficiency, step-down, switching converter and a o Wide 2.0V to 5.5V Operating Input 100mA LDO regulator. The nA quiescent Range current provides extremely high efficiency when o Seven Selectable Output Voltages the load current is in the A range. With the o Up to 700mA Output Current minimum input voltage as low as 2V, the o 1.5MHz Switching Frequency in MP28301 allows the system to operate directly Continuous Conduction Mode (CCM) from the battery. o 100% Duty Cycle in Dropout o 0.25 and 0.25 Internal Power The constant-on-time (COT) control scheme MOSFET Switches provides fast transient response, high light-load o Cycle-by-Cycle Over-Current Protection efficiency, and requires minimal capacitance. (OCP) The regulation is made tight by integrating an o Short-Circuit Protection (SCP) with error amplifier to correct the output voltage. Hiccup Mode A 100mA LDO regulator provides easy system 100mA LDO configuration with a clean output voltage. o Ultra-Low I : 300nA Q o 2.0V to 5.5V Operating Input Range The CTRL pins control the on/off and output o Three Selectable Output Voltages voltage selection functions. o Over-Temperature Protection (OTP) Fault protection features include under-voltage Available in a QFN-12 (2mmx2mm)Package lockout (UVLO), over-current protection (OCP), APPLICATIONS and thermal shutdown. Wearables The MP28301 requires a minimal number of IoT Devices readily available, standard, external Portable Instruments components and is available in a small QFN-12 Battery-Powered Devices (2mmx2mm) package.
