Linentery launches high temperature and high reliability version of LT3690

MILPITAS (Linear Technology CorporaTIon) launched the LT3690 high temperature (H level) and high reliability (MP grade) version. This accepted 36V input synchronous buckle switch regulator provides up to 4A continuous output current at up to 93% efficiency. LT3690 operates within a VIN range of 3.9V to 36V, 60V transient protection is provided, ideal for applications in the automotive load dump and cold-crank conditions. LT3690 requires only 70uA of quiescent current when operating in burst mode (Burst Mode®), well suited for applications such as automotive or telecom systems, such applications require always-on operation and optimum battery life. Switching frequency is user-programmable, in the range of 170kHz to 150MHz, enabling the designer to optimize efficiency while avoiding critical noise-sensitive frequency bands. 4mm x 6mm QFN-26 package combining the device with high switching frequency allows the use of small external inductors and capacitors, thereby constituting a compact footprint, thermally efficient solution. Be H-grade version? C in the temperature range section of work in -40? C to 150, and assurance and testing in this temperature range. Similarly, MP-grade version? C in the temperature range section of work in -55? C to 150 within this temperature range is tested and guaranteed. H and MP-level electrical codes and E and I are the same level. They are ideal for automotive, industrial and military applications, such applications are at high ambient temperatures. Be LT3690HUFE and 26 are used LT3690MPUFE lead 4mm x 6mm QFN package. Thousand approved purchase price of $ 5.70 and $ 14.70 per sheet, are available from stock.
