Maxim Integrated Products, Inc. introduces power management integrated circuits that offer a smaller, more efficient solution size to help automotive designers meet the power and space challenges of next-generation automotive applications.Digital instrumentation equipment, radio central units, and electronic systems require higher levels of computing power; these new high-power converters and high-power, multi-phase controllers allow designers to balance low power consumption with high efficiency and mitigation of electromagnetic interference (EMI).
Maxim's automotive integrated circuit range offers numerous options for managing DC power as OEMs move away from processors that consume up to 500 watts. With a package size of 3.5 mm x 3.75 mm, Maxim converters offer the smallest solution size in the industry. Their Flip-Chip Quad Flat No Lead (FCQFN) package reduces high-frequency switching nodes and eliminates links to lower MOSFET switch on-resistance and increase efficiency. Maxim offers the industry's only pin-compatible parts for four, six, and eight amps for flexible power regulation. All ICs feature wide spectrum modulation, high switching frequency, forced pulse-width modulation, and hop-mode operation for best-in-class performance.
Maxim's newest automotive power management integrated circuits for high-voltage power applications include:
The MAX20004, MAX20006, and MAX20008 4A, 6A, and 8A high-voltage (40V tolerant) synchronous buck converters with integrated Hs and Ls MOSFETs offer the industry's lowest resistance of 38 and 18 mΩ, respectively, for high efficiency. Key advantages of these pin-compatible devices include a quiescent current of 25 μA, operating input voltages from 3.5V to 36V, and 93% peak efficiency. All are available in a 17-pin, 3.5 mm x 3.75 mm QFN package that reduces high-frequency switching and improves efficiency.
The MAX20098 220kHz to 2.2MHz synchronous buck driver is designed for high-power applications with input voltages from 3.5V to 36V (42V tolerant). For increased efficiency, this device features a 3.5μA (skip mode) current at a 3.3V output, along with a typical turn-off current specification of 1μA. Its 3mm x 3mm side-wettable QFN package reduces the solution size, and the IC requires few external components, enabling a two-layer PCB design.
The MAX20034 dual 220 kHz to 2.2 MHz synchronous buck converter for high-voltage applications operates with input voltages from 3.5 V to 36 V (42 V tolerant), where one regulator functions as a fixed 5 V or 3.3 V output and the other output can be adjusted from 1 V to 10 V. Key efficiency advantages include a quiescent current of 17 μA (skip mode) and a typical turn-off current of 6.5 μA. The device is available in a 5 mm x 5 mm side-wettable QFN package and offers up to 2.2 MHz switching speeds, reducing the need for external components and overall solution size.
