Automotive OEMs often limit instrument cluster module consumption to less than 100 µA in standby mode. Given all the functions that the instrument cluster performs, the power supply itself must consume only a tiny portion of the power budget. Under no-load conditions, the MAX16993 is, Maxim claims, the only 3-channel solution on the market that consumes 25 µA of quiescent current. This makes the PMIC more efficient than traditional DC-DC converters, which often run on several milliamps. The MAX16993 integrates a high-switching-frequency controller and two output converters capable of 3A each; it saves over 50% board space compared to traditional discrete solutions. The device’s 2.1 MHz switching frequency improves AM band noise avoidance and keeps the external inductors and capacitors small. Use it in automotive instrument clusters and infotainment applications.

It occupies a 5 x 5 x 0.75 mm, 32-pin TQFN-EP or a 5m x 5m x 0.8 mm, side-wettable QFND-EP package; it is AEC-Q100 qualified and operates over the -40°C to +125°C automotive temperature range. Pricing starts at $5.39 (1000).
