TI Introduces First Automotive-grade, Multi-phase Synchronous Boost Controller With Up To 100-V Output Voltage

Key features and benefits of the LM5122Q boost controllers:

  • 100-V output range and 65-V input range simplifies high-voltage design.
  • High power density is easily achieved with interleaved multi-phase operation.
  • Bypass feature enables pass-through of input to output when boost functionality is not required.
  • User-selectable diode emulation enables improved efficiency at light load conditions.

Key features and benefits of the TPS43060 and TPS43061 boost controllers:

  • 500-uA quiescent current supports battery-powered applications.
  • Up to 1-MHz operation allows small inductor and ceramic capacitors, which reduces overall solution size.
  • -40 degrees C to 150 degrees C operating junction temperature for robust performance in hotter environments.

Availability, packaging and pricing

The TPS43060 and TPS43061 are available in volume now from TI and its authorized distributors. Offered in a 16-pin QFN PowerPad™ package that measures 3 mm by 3 mm by 0.75 mm, the TPS43060 and TPS43061 are priced at $1.40 in 1,000-unit quantities.

Samples and production quantities of the LM5122Q are expected to be available in the second quarter. Offered in a 20-pin TSSOP package that measures 6.5-mm by 4.4-mm by 0.9-mm, the LM5122Q is priced at US$2.10 in 1,000-unit quantities.
