MP2192GC-P

MP2192 2A, 2.5V to 5.5V, Synchronous Step-Down Converter with 25µA IQ in CSP Package DESCRIPTION FEATURES The MP2192 is a monolithic, step-down switchmode converter with built-in internal power MOSFETs. The MP2192 achieves 2A of continuous output current from a 2.5V to 5.5V input voltage, with excellent load and line regulation. The output voltage can be regulated to as low as 0.6V.         Constant-on-time (COT) control provides fast transient response and eases loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown. The MP2192 is well-suited for a wide range of applications, including high-performance DSPs, wireless power, portable and mobile devices, and other low-power systems. The MP2192 requires a minimal number of readily available, standard external components. It is available in an ultra-small CSP-6 (0.85mmx1.25mm) package.       Low 25μA IQ 1.1MHz Switching Frequency EN for Power Sequencing 1% FB Accuracy Wide 2.5V to 5.5V Operating Input Range Output Adjustable from 0.6V Up to 2A Output Current 75mΩ and 45mΩ Internal Power MOSFET Switches 100% Duty Cycle Output Discharge VOUT Over-Voltage Protection (OVP) Short-Circuit Protection (SCP) with Hiccup Mode Available in a WLCSP-6 (0.85mmx1.25mm) Package Excellent Transient Response with Minimal Output Capacitors Optimized Performance with MPS Inductor MPL-AL4020 Series APPLICATIONS     Solid State Drives (SSDs) Portable Instruments Battery-Powered Devices Multi-Function Printers All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.

OUT is the voltage power rail and input sense pin for the output voltage. Use an output capacitor to reduce the output voltage ripple. B1 SW Output switching node. SW is the drain of the internal high-side P-channel MOSFET. Connect the inductor to SW to complete the converter. B2 EN On/off control. C1 VIN Supply voltage. The MP2192 operates from an unregulated input between 2.5V and 5.5V. A decoupling capacitor is required to prevent large voltage spikes from appearing at the input. C2 FB Feedback. An external resistor divider connected from the output to GND, then tapped to the FB pin, sets the output voltage.
