Maxim Introduces Automotive-Grade, Quad-Output Controller That Operates From Up to 38V
Maxim Integrated Products introduced the MAX17019, a high-input-voltage, quad-output controller for automotive applications. According to the company, the device saves space and cost by integrating four independent voltage outputs in a small, 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 that does not sacrifice transient response. This architecture also supports peak-current-limit protection and pulse-skipping operation to maintain high efficiency under light-load conditions.
The MAX17019 is available in a space-saving, 6 x 6mm, 48-pin TQFN package, and is fully specified over the -40 to +125°C automotive temperature range. Prices start at $5.50 (1000-up, FOB USA).
