MPM3811GG-Z

MPM3811 2.3V - 5.5V Input, 1A Power Module in Small 2x2x1.6mm QFN Package DESCRIPTION FEATURES The MPM3811 is a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs and an inductor. The MPM3811 achieves 1A of continuous output current from a 2.3V to 5.5V input voltage with excellent load and line regulation. The MPM3811 is ideal for a wide range of applications, including high performance DSPs, wireless power, portable and mobile devices, and other lowpower systems. The output voltage can be regulated as low as 0.6V. Only input capacitors, output capacitors, and feedback (FB) resistors are needed to complete the design.         The constant-on-time (COT) control scheme provides fast transient response, high light-load efficiency, and easy loop stabilization.   Full protection features include cycle-by-cycle current limiting and thermal shutdown.  The MPM3811 requires a minimal number of readily available, standard, external components and is available in an ultra-small QFN-10 (2mmx2mmx1.6mm) package. APPLICATIONS          Up to 91% Peak Efficiency Wide 2.3V to 5.5V Operating Input Range Output Voltage as Low as 0.6V 100% Duty Cycle in Dropout 1A Output Current 2.2MHz Frequency EN for Power Sequencing Cycle-by-Cycle Over-Current Protection (OCP) 0.5ms Internal Soft-Start (SS) Time Output Discharge Short-Circuit Protection (SCP) with Hiccup Mode Thermal Shutdown Stable with Low ESR Output Ceramic Capacitors Available in a QFN10 (2mmx2mmx1.6mm) Package Optical Modules IoT Devices Handheld Printers/POS Portable Devices Low Voltage I/O System Power Space-Constraint Systems All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.

The MPM3811 operates from a +2.3V to +5.5V unregulated input range. A decoupling capacitor is needed to prevent large voltage spikes from appearing at the input. Output switching node. SW is the drain of the internal, high-side, P-channel MOSFET. SW is not for testing and is for internal use only. On/off control. Output voltage power rail and input sense pin for output voltage. Connect the load to OUT. An output capacitor is needed at OUT to decrease the output voltage ripple. Feedback. An external resistor divider from the output to GND tapped to FB sets the output voltage.
