LTC1438IG-ADJ#PBF Product Details
LTC1438IG-ADJ#PBF Overview
As a result of 28-SSOP (0.209, 5.30mm Width) compact design, the switching controller is compatible with most applications. dc motor controller is suitable for 2 output generation. Tube solid enclosure protects the pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's3.5V~30V is the supply voltage and the operating voltage of the dc control. Suitable for a -40°C~85°C TA dc switcher. This switching controller can switch at Up to 400kHz. Surface Mount makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Power on Reset, Soft Start. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. DUAL are the position of the terminal of the switching converters. Different dc switching's functions can be applied to 28 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "LTC1438". Switching converter has a total of 28 pins. Switching converter type is specifically Switching Regulator or Controllers. Statistically, DC regulator outputs 9V volts. In most cases, the dc dc regulator's output current is 2A. This information should be noted when you begin working with the component. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. 138kHz is the maximum frequency of this dc regulators. Switching controller is necessary to have a supply voltage of 3.5V.
