Intended for low to medium power applications in high temperature environments up to 175°C, the LTC1871X eliminates the need for a current sense resistor by using the power MOSFET’s on-resistance, thereby maximizing efficiency.
The 2.5V to 36V input voltage range is suited to high temperature applications such as oil exploration drilling equipment with power sources ranging from 3V to 36V as the electrical parameters are 100% tested at 175°C, offering a VREF accuracy of ±2% over the entire –40°C to 175°C temperature range.
The flexibility for boost, SEPIC or flyback topologies supports a wide range of battery-powered applications commonly found in downhole drilling applications, and the Burst Mode operation offers low quiescent current, well suited for applications that require extended operating battery life.
Specialized Cu/Ni/Au bond pad plating ensures long life in high temperature environments while a tiny MSOP-10 package offers a highly compact solution footprint.
The LTC1871XMS, offered in an MSOP-10 package, is priced at $125.00 each in 1,000-piece quantities and is available from stock.
