Texas Instruments has unleashed two families of wide input voltage DC/DC buck regulators with electromagnetic interference (EMI) and thermal performance good enough to simplify the process of achieving EMI compliance and higher reliability for rugged industrial and automotive power supplies.
The highly integrated 5A and 6A LM73605/6 and 2.5A and 3.5A LM76002/3 step-down voltage converters feature an optimized pinout and thermal coefficient ideal to simplify EMI compliance and higher reliability for rugged industrial and automotive power supplies.
The new devices include 5A and 6A LM73605/6 and 2.5A and 3.5A LM76002/3 DC/DC step-down buck converters.
They provide up to 60V operating input voltage range for nominal 12V, 24V or 48V systems such as remote radio units, ultrasound scanners, motor drives, inverters and servo control units.
The regulators offer up to 92 percent full load efficiency at 12 VIN, 5 VOUT and 500 KHz switching frequency. Very low 15-µA standby quiescent current increases light load efficiency.
The automotive-grade LM76002-Q1, LM76003-Q1, LM73605-Q1 and LM73606-Q1 support compact automotive applications such as the infotainment head unit and front/surround-view cameras used for autonomous driving.
“The 3.5-V to 36-V LM73605/6 and 3.5-V to 60-V LM76002/3 buck regulators meet and exceed the demanding CISPR 25 Class 5 automotive electromagnetic compatibility (EMC) requirements. These regulators’ programmable output switching frequency can be set either above the AM band, which eliminates AM-band interference and reduces output filter size and cost, or below the AM band to optimize efficiency”, according to TI.
Offered in a 30-pin, 4-mm-by-6-mm WQFN package, the LM73605 and LM73606 are priced in small reels at US$2.93 for 1,000-unit quantities, and the LM76002 and LM76003 are priced at US$2.88.
