DescriptionThe LTC1622IS8 is one member of the LTC1622 family which is designed as one kind of low input voltage current mode step-down DC/DC controller that can be used in (1)One or Two Lithium-Ion-Powered Applications; (2)Cellular Telephones; (3)Wireless Modems; (4)RF Communications; (5)Distributed 3.3V, 2.5V or 1.8V Power Systems; (6)Scanners; (7)Battery-Powered Equipment. And this device incorporates an accurate undervoltage feature that shuts the LTC1622 down when the input voltage falls below 2V.
Features of the LTC1622IS8 are:(1)High Efficiency; (2)Constant Frequency 550kHz Operation; (3)VIN Range: 2V to 10V; (4)Multiampere Output Currents; (5)Synchronizable up to 750kHz; (6)Selectable Burst Mode Operation; (7)Low Dropout Operation: 100% Duty Cycle; (8)Current Mode Operation for Excellent Line and Load Transient Response; (9)Low Quiescent Current: 350A; (10)Shutdown Mode Draws Only 15A Supply Current; (11)±2.5% Reference Accuracy; (12)Available in 8-Lead MSOP.
The absolute maximum ratings of the LTC1622IS8 can be summarized as:(1)Input Supply Voltage (VIN):-0.3V to 10V;(2)RUN/SS, VFB Voltages: -0.3V to 2.4V;(3)ITH Voltage: -0.3 V to 5 V;(4)SYNC/MODE Voltage:-0.3V to VIN;(5)SENSE Voltage:2.4V to (VIN + 0.3V);(6)PDRV Peak Output Current (<10us):1 A;(7)operating temperature range commercial:0°C to 70°C;(8)storage temperature range:-65°C to 150°C;(10)lead temperature (soldering, 10 sec):300°C.
