Maxim Integrated Products, Inc. announced power-management ICs offering the smallest solution size and high efficiency to help automotive designers meet space and power challenges of next-generation automotive applications. As digital instrument clusters, radio head units and electronic subsystems require ever higher levels of compute power, these new high-power buck converters and high-power, multiphase buck controllers empower designers to balance low power consumption with high efficiency and electromagnetic interference mitigation. 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 mO, respectively, for high efficiency. Key advantages of these pin-compatible devices include 25µA quiescent current, operating input voltages from 3.5V to 36V and 93% peak efficiency. All are available in a compact 3.5mm x 3.75mm, 17-pin side-wettable QFN package that reduces high-frequency switch node and improves 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. For efficiency, this device features a quiescent current of 3.5µA in skip mode at 3.3V output along with a 1µA typical shutdown current specification. Its 3mm x 3mm side-wettable QFN package reduces solution size, and the IC requires few external components, enabling a two-layer PCB design. 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. Key efficiency advantages include 17µA quiescent current in skip mode and 6.5µA typical shutdown current. The device is available in a 5mm x 5mm side-wettable QFN package, and it provides up to 2.2MHz switching frequency to enable smaller external components and total solution size.
