Ling Li, the special company introduces the stepping down stabilizator LTC3608 synchronously of high efficiency
Ling Li belong to special company (Linear Technology Corporation) Introduce the high efficiency, stepping down synchronously steady transformer LTC3608, this device can offer the high serial output current up to 8A when the voltage is low to 0.6V. LTC3608 is from 4V to 18V (absolute maximum value is 20V) Input work in voltage range,is it multinode without being adopted to suitable for lithium battery, lead acid cell or high to reach 15V fixed voltage the applications of the rails very. Its current control framework of valley value realizes very low duty ratio works by the remarkable transient response when high-frequency. Operating frequency is set up by a external resistance. The high switching frequency up to 1MHz allows to use small-scale, low-cost ceramic capacitors and tabular inductors.
LTC3608 uses RDS (ON) It is only 10mΩ And 8mΩ Switches internal,in order to offering it is high reach 95% efficiency. LTC3608 can configure to the make-and-break or force the continuous work. Force reducible noise and RF of the continuous work to interfere with, and the disconnected Discontinuous Conduction mode has offered the high efficiency through the switching loss when reduced the light load, its requirement 900uA quiescent current. The quiescent current during shutting down is only 15uA. Other characteristic including power good voltage monitor, adjustable electric current have limited, exported and pressed and protected programmable soft turn on.
Adopt LTC3608EWKG that 52 lead wire, 7mm x 8mm QFN capsulate to supply from stock. Regard 1,000 as the unit to buy in batches, each price is 7.50 dollars. The edition LTC3608IWKG of technical grade guarantees to be here through testing - 40& deg; C To 125& deg; C Working for junction temperature work in range,a thousand sheets buy goods wholesale there are chip 8.63s every on price. All editions supply from stock.
