PMIC suits automotive instrument clusters

The MAX16993 PMIC targets automotive instrument clusters. It is the only 3-channel solution that consumes 25-μA quiescent current, enabling automotive OEMs to meet the 100 μA standby mode requirement for instrument clusters. The device integrates a high-switching-frequency controller and two output converters capable of 3 A each and it saves over 50% board space compared to traditional discrete solutions.

The PMIC operates at 2.1 MHz, which improves AM-band noise avoidance and keeps the external inductors and capacitors small. The chip provides a spread-spectrum that help minimize radiated electromagnetic interference and includes factory-programmable synchronization I/O to allow better noise immunity. It is available in a 5 x 5 x 0.75-mm, 32-pin TQFN-EP and a 5 x 5 x 0.8-mm, side-wettable QFND-EP package. The device is AEC-Q100 qualified and operates from –40° to +125°C.
