Maxim MAX20073 and MAX20074 compact synchronous buck converters

The pin-compatible MAX20073 and MAX20074 buck converters, from Maxim Integrated Products, offer low EMI performance for low-voltage point-of-load applications and are suitable for automotive infotainment and ADAS.

The compact converters feature high efficiency and low EMI, reducing interference that can impact the function of subsystems in a small solution size with ultralow quiescent current. Combined with the company’s spread spectrum oscillator, SYNC IN functionality, forced PWM, skip modes and current-mode architecture, the system quality and performance improves, easing overall system designs.

The backend point-of-load (POL) buck converters send specific voltage to the many power rails that come with advanced modern features. Their output voltage accuracy makes them suitable for applications that have tight processor and memory voltage requirements. The ICs also adhere to tight safety standards, operate with low-input voltages across a wide range of temperatures and minimise radiofrequency interference (RFI) while exhibiting high efficiency.

The product’s small 3 x 3 mm 10-pin TDFN-EP package reduces overall system footprint, while saving system BOM cost. Output voltage can be preset at the factory to allow ±1.5% output-voltage accuracy without the need for 0.1% external resistors.
