Maxim’s Power Management ICs offer low quiescent current, improved noise performance and EMI mitigation for digital instrument clusters and radio head units

Maxim Integrated Products announced power-management IC Solutions, to help automotive designers meet space and power challenges of next-generation automotive applications.

To ensure designers achieve the performance needed in harsh, space-constrained automotive operating environments, Maxim’s array of automotive-grade ICs provide many options to manage the DC power as automotive OEMs transition from processors that consume 20 watts of power to artificial intelligence platforms that consume as much as 500 watts.

With a package size of 3.5mm x 3.75mm, Maxim’s buck converters offer the smallest solution size. Their FCQFN packaging reduces high-frequency switch node ringing and eliminates bond wires to lower MOSFET switch on-resistance and increase efficiency. All of the ICs feature spread-spectrum modulation, high switching frequency, forced pulse-width modulation and skip-mode operation for best-in-class performance.

Maxim’s newest automotive power-management ICs for high-voltage power applications include MAX20004, MAX20006 and MAX20008 4A, 6A and 8A high-voltage synchronous buck converters with integrated high-side and low-side MOSFETs, offering the industry’s lowest switch resistance of 38 and 18 mΩ, respectively, for high efficiency.

MAX20098 220kHz to 2.2MHz synchronous buck controller for applications with mid- to high-power requirements operating with input voltages from 3.5V to 36V (42V tolerant). MAX20034 220kHz to 2.2MHz dual synchronous buck controller for high-voltage applications operating with input voltages from 3.5V to 36V, where one regulator will operate as a fixed 5V or 3.3V output and the other output is adjustable between 1V to 10V.
