PMIC combines 3 DC/DC converters saving over 50% board space
Consuming just 25µA of quiescent current, the MAX16993 PMIC enables smaller, quieter, and more efficient automotive clusters. Maxim claim that, under no-load conditions, their product is the only 3-channel solution on the market today.
The 25µA of quiescent current makes the PMIC more efficient than traditional DC-DC converters, which often run on several milliamps. Further to this, the IC integrates a high-switching-frequency controller and two output converters capable of 3A each, saving over 50% board space when compared to traditional discrete ICs. Improving AM band noise avoidance, the device's 2.1MHz frequency also keeps the external inductors and capacitors small.
“The MAX16993 offers many best-in-class features in a single chip,” commented Dan Dempsey, Executive Director in the Automotive Business Unit at Maxim Integrated. “As a result, the MAX16993 is a highly efficient automotive power solution for today’s instrument clusters.”
The device is offered in a 5 x 5 x 0.75mm, 32-pin TQFN-EP and a 5 x 5 x 0.8mm, side-wettable QFND-EP package. AEC-Q100 qualified, the device operates over the -40°C to +125°C automotive temperature range. The MAX16993 is suitable for automotive instrument clusters and infotainment applications.Prices for the device start at at $5.39.
