EVM3810-QB-01A Monolithic Power Systems

EVM3810-QB-01A 6V, 1.2A Peak Synchronous Step-Down Switcher Evaluation Board The Future of Analog IC Technology DESCRIPTION FEATURES The EVM3810-QB-01A is used for Wide 2.5V to 6V Operating Input Range demonstrating the performance of MPSs Fixed and Adjustable output from 0.6V MPM3810 a low voltage high switching 3mm x 2.5mm x 0.9mm QFN Package frequency step-down switcher with built-in Total Solution Size 6mm x 3.8mm power MOSFETs and power inductor. Up to 1.2A Peak Output Current MPM3810 provides up to 1.2A peak highly 100% Duty Cycle in Dropout efficient output with constant-on-time control for Ultra Low IQ: 17 A fast loop response. EN and Power Good for Power Sequencing High power efficiency over a wide load range is Cycle-by-Cycle Over-Current Protection achieved by scaling down the switching Short Circuit Protection with Hiccup Mode frequency at light load to reduce the switching Adjustable Output Only Needs 4 External related loss by constant on time control. Short Components - 2 Ceramic Capacitors and circuit and thermal shutdown provides reliable, FB Divider Resistors fault-tolerant operation. Fixed Output Only Needs Input and Output MPM3810 is available in QFN 3.0x2.5x0.9mm Capacitors package.
