element14 introduces step-down regulator from Linear Technology for automotive applications

Bangalore, India, April 27 2015: element14 has introduced Linear Technology’s LT8609, a 2A, 42V input synchronous step-down switching regulator with unique synchronous rectification topology that delivers 93% efficiency while switching at 2MHz. This enables designers to avoid noise-sensitive frequency bands, such as AM radio, while providing a highly compact package; it is available in a small 10-lead thermally-enhanced MSOP package.

Suited for applications requiring general purpose step-down or low EMI step down, the LT8609 features : 

  • Wide Input Voltage Range: 3.0V to 42V
  • Ultra-low Quiescent Current Burst Mode Operation
  • <2.5μA IQ Regulating 12VIN to 3.3VOUT
  • Output Ripple <10mVP-P
  • High Efficiency 2MHz Synchronous Operation (93% Efficiency at 1A, 5VOUT from 12VIN)

The LT8609’s 3.0V to 42V input voltage range makes it ideal for automotive applications which must regulate through cold-crank and stop-start scenarios with minimum input voltages as low as 3.0V and load dump transients in excess of 40V. The LT8609’s feature set is rounded off by internal compensation, a power good flag, output soft start/tracking and thermal protection.
