MP3427GL-P

MP3427 17A, 600kHz, 8V Wide Input Range Synchronous Boost Converter in a small 3x4mm QFN Package The Future of Analog IC Technology DESCRIPTION FEATURES The MP3427 is a 600kHz fixed-frequency, high- 3V-to-8V Wide Input Range efficiency, wide input range, current-mode Integrated 10m Low-Side Power FET boost converter with optional internal or SDR Driver for Synchronous Solution external current-sensing configuration for high- >17A Switch-Current Limit integration and high-power applications. With a Optional Internal/External Current- current limit above 17A, the MP3427 supports Sensing Configuration up to 30W load power from Li-ion battery input. External Soft-Start and Compensation for The MP3427 features a 10m power switch Higher Flexibility and a synchronous gate driver for high Programmable UVLO and Hysteresis efficiency. An external compensation pin gives < 1A Shutdown Current the user flexibility in setting loop dynamics and o Thermal Shutdown at 150 C obtaining optimal transient performance at all Available in a 3x4mm QFN-22 Package conditions. APPLICATIONS The MP3427 includes under-voltage lockout (UVLO), switching-current limiting and thermal Tablets shutdown (TSD) to prevent damage in the Power Banks event of an output overload. Fuel Cells POS Systems The MP3427 is available in a low-profile 22-pin Electronic Cigarettes 3mmx4mm QFN package. All MPS parts are lead-free and adhere to the RoHS directive.
