DescriptionThe LTC3711EGN is one member of the LTC3711 family which designed as one kind of synchronous step-down switching regulator controller for CPU power.It uses a valley current control architecture to deliver very low duty cycles without requiring a sense resistor.And the internal foldback current, limiting, an output overvoltage comparator and optional short-circuit shutdown timer provided the fault protection.So it can be used in notebook and palmtop computers, PDAs; power supplies for mobile pentium® processors.
Features of the LTC3711EGN are:(1)5-bit programmable output voltage: 0.925v to 2v; (2)no sense resistor required; (3)true current mode control; (4)2% to 90% duty cycle at 200khz; (5)ton(min) < 100ns; (6)supports active voltage positioning; (7)extremely fast transient response; (8)stable with ceramic cout; (9)dual n-channel mosfet synchronous drive; (10)power good output voltage monitor; (11)wide vin range: 4v to 36v; (12)±1% 0.8v reference; (13)adjustable current limit; (14)adjustable switching frequency; (15)programmable soft-start; (16)output overvoltage protection; (17)optional short-circuit shutdown timer; (18)micropower shutdown: iq < 30ma; (19)available in 24-lead narrow ssop package.
The absolute maximum ratings of the LTC3711EGN can be summarized as:(1)lead temperature (soldering, 10 sec):300°C;(2)storage temperature range:-65°C to 150°C;(3)junction temperature:125°C;(4)operating ambient temperature range:-40°C to 85°C;(5)boosted topside driver supply voltage:42V to -0.3V.If you want to know more information such as the electrical characteristics about the LTC3711EGN,please download the datasheet in www.seekic.com or www.chinaicmart.com .
