MPQ9840 36V, 3.5A, Low I , Q Synchronous Step-Down Converter AEC-Q100 Qualified The Future of Analog IC Technology DESCRIPTION FEATURES The MPQ9840 is a high-frequency, 2 A Low Shutdown Supply Current synchronous, rectified, step-down, switch-mode 14 A No-Load Quiescent Current converter with built-in power MOSFETs. It Internal 125m High-Side and 55m Low- offers a very compact solution that achieves Side MOSFET 3.5A of continuous output current with excellent 350kHz to 2.5MHz Programmable Switching load and line regulation over a wide 3.3V to 36V Frequency input supply range. The switching frequency Power Good (PG) Output can be programmed or synchronized to an External Soft Start (SS) external clock in the range of 350kHz to 80ns Minimum On Time 2.5MHz. The synchronous operation and ultra- Selectable Forced CCM and AAM low 14 A sleep mode quiescent current provide Hiccup Over-Current Protection (OCP) high efficiency over the output current load AEC-Q100 Grade-1 range, allowing the MPQ9840 to be used in a Available in a QFN-16 (3mmx4mm) variety of step-down applications in automotive Package input environments and battery-powered applications. APPLICATIONS Peak-current-mode operation provides fast Automotive Systems transient response and eases loop stabilization. Industrial Power Systems The excellent low dropout performance allows All MPS parts are lead-free, halogen-free, and adhere to the RoHS the MPQ9840 to be used in high duty cycle directive.
