Automotive-grade quad-output controller IC

Maxim Integrated Products has introduced the MAX17019, a high-input-voltage, quad-output controller for automotive applications. This device saves space and cost by integrating four independent voltage outputs in a 36mm2 TQFN package. The device includes a main-stage step-down controller, a 3Ap-p step-down regulator, a 5Ap-p step-down regulator and a 2A source/sink linear regulator. Capable of operating up to 38V, the MAX17019 is suitable for automotive battery-powered devices. The step-down converters use a peak-current-mode, fixed-frequency control scheme to provide an easy-to-implement architecture without compensating the transient response. This architecture also supports peak-current-limit protection and pulse-skipping operation to maintain high efficiency under light-load conditions. This controller IC is available in 6x6mm, 48-pin TQFN package and is fully specified over -40ºC to +125ºC automotive temperature ranges.
