MPQ2454-AEC1 36V, 0.6A Step-Down Converter AEC-Q100 Qualified DESCRIPTION FEATURES The MPQ2454 is a frequency-programmable 60A Operating Quiescent Current (350kHz to 2.3MHz) step-down switching Wide 3.3V to 36V Operating Input Range regulator with an integrated internal high-side, 200m Internal Power MOSFET high-voltage power MOSFET. It outputs Up to 2.3MHz Programmable Switching efficiently up to 0.6A and has current-mode Frequency control for fast loop response. Stable with Ceramic Output Capacitors Internal Compensation The wide 3.3V to 36V input range accommodates a External Soft-Start variety of step-down applications in automotive- input environments. A 3.5A shutdown-mode > 90% Efficiency quiescent current allows for use in battery- Low Dropout Operation for Cold-Crank powered applications. Also, the device has a high 3.5A Low Shutdown Supply Current duty cycle and low drop-out mode for automotive Synchronization to External Clock cold-crank conditions. Power Good Output Programmable Power Good Delay Time The MPQ2454 achieves high-power conversion MSOP-10 EP and QFN-10 (3mmx3mm) efficiency over a wide load range by scaling Packages down the switching frequency at light-load Available in AEC-Q100 Grade 1 conditions to reduce both switching and gate driving losses. APPLICATIONS Frequency foldback prevents inductor current High-Voltage Power Conversion runaway during start-up and short circuit. Automotive Systems Thermal shutdown provides reliable, fault-tolerant Industrial Power Systems operation. An open-drain power good (PG) signal Distributed Power Systems indicates when the output is within its nominal Battery Powered Systems voltage. All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For The MPQ2454 is available in MSOP-10 EP and MPS green status, please visit the MPS website under Quality Assurance.
