The LT8610AX 3.5A, 42V input capable synchronous step-down switching regulator operates in ambient temperatures up to 175°C. Synchronous rectification delivers efficiency as high as 95% while Burst Mode operation keeps quiescent current under 3.5 µA in no-load standby conditions. Electrical parameters are 100% tested at +175°C, offering a VREF accuracy of 2% over the entire -+40°C to +175°C temperature range. At ambient temperatures of +175°C, the LT8610AX offers over 90% efficiency (for 12 VIN to 3.3VOUT conversions) over a load current range of 10 mA to 1A, Additionally, the device comes in a 16-lead thermally enhanced MSOP. Price is $125 each/1,000. For more information, visit http://www.linear.com/product/LT8610AX
