Linear200kHz stepping down DC/DC converter has the highest junction temperature of 140oC and only consumes 100u
Ling Li, the special company puts out the stepping down steady transformer LT3437 of switch of H grade. This device takes from 3.3V to the serial input of 60V, can bear the high transient voltage up to 80V, very suitable for car and telecommunication application. The switch offers the high serial output current up to 400mA when the voltage is low to 1.25V within its 500mA. The burst mode (Burst Mode? )The work drops the non-loaded quiescent current to low in 100uA, has lengthened and put through the operation time of applied battery all the time to the maximum extent.
H One grade of devices is through testing, guarantee the normal operation in 140oC junction temperature, and E grade and I grade device stipulate the highest junction temperature is 125oC. All electrical performance specifications of E, I and H grade device are identical. The LT3437 H grade device is very suitable for car and industrial application, and this kind of application needs to bear the high ambient temperature.
Adopt LT3437HFE that TSSOP-16E capsulates to supply from stock. Regard 1,000 as the unit to buy in batches, each slice of trigger price is 3.00 dollars.
