MAX20004E/MAX20006E/ Automotive, 36V, 4A/6A/8A Integrated Step- MAX20008E Down Converters with Integrated Compensation General Description Benefits and Features The MAX20004E/MAX20006E/MAX20008E are small, Multiple Functions for Small Size synchronous buck converters with integrated high-side Operating V Range of 3V to 36V IN and low-side MOSFETs. The device family can deliver 15A Quiescent Current in Skip Mode up to 8A with input voltages from 3.5V to 36V, while Synchronous DC-DC Converter with Integrated using only 15A quiescent current at no load (except for FETs MAX20006EAFOD/VY+ which has FPWM mode only). 400kHz or 2.1MHz Switching Frequency Voltage quality can be monitored by observing the RESET Fixed 5ms(default) Internal Soft-Start signal. The devices can operate in dropout by running at 3.3V/3.9V/5.0V Fixed Output Options 98% duty cycle, making them ideal for automotive applica- 98% Duty-Cycle Operation with Low Dropout tions. RESET Output The devices offer fixed output voltages of 5V, 3.9V, or High Precision 3.3V. Compensation is internal to the device, providing 2% Output-Voltage Accuracy excellent transient response. Frequency can be 400kHz Good Load-Transient Performance or 2.1MHz. The devices offer a forced fixed-frequency Robust for the Automotive Environment mode and skip mode with ultra-low quiescent current of Current-Mode, Forced-PWM, and Skip Operation 15A. The device has a pin-selectable (SSEN) spread- Overtemperature and Short-Circuit Protection spectrum enable to further assist systems designers with 3.5mm x 3.75mm 17-Pin FC2QFN better EMC management. Symmetrical Pinout with Pin-Selectable Spread The MAX20004E/MAX20006E/MAX20008E are available Spectrum for Optimized EMI Performance in a small 3.5mm x 3.75mm 17-pin FC2QFN package and -40C to +150C Junction Operating Range use very few external components. 40V Load-Dump Tolerant AEC-Q100 Qualified Applications Ordering Information appears at end of datasheet.
