Description

The MAX20004E/MAX20006E/MAX20008E are small, synchronous buck converters with integrated high-side and low-side MOSFETs. The device family can deliver up to 8A with input voltages from 3V to 36V, while using only 15µA quiescent current at no load (except for MAX20006EAFOD/VY+ which has FPWM mode only). Voltage quality can be monitored by observing the active-low RESET signal. The devices can operate in dropout by running at 98% duty cycle, making them ideal for automotive applications.The devices offer fixed output voltages of 5V, 3.9V, or 3.3V. Compensation is internal to the device, providingexcellent transient response. Frequency can be 400kHz or 2.1MHz. The devices offer a forced fixed-frequencymode and skip mode with ultra-low quiescent current of 15µA. The device has a pin-selectable (SSEN) spread-spectrum enable to further assist systems designers with better EMC management. The MAX20004E/MAX20006E/MAX20008E are available in a small, 3.5mm x 3.75mm, 17-pin FC2QFN package and use very few external components.ApplicationsADASDistributed DC Power SystemsNavigation and Radio Head UnitsPoint-of-Load Applications in Automotive
