LTC1438CG#PBF Product Details
LTC1438CG#PBF Overview
Capsuled in the 28-SSOP (0.209, 5.30mm Width) package, the switching controller can be used for a wide range of applications. 2 outputs can be generated with the dc motor controller. There is a Tube solid enclosure around the pmic. The system can process Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 3.5V~30V. Qualified to work in a 0°C~70°C TA dc switcher. In this switching controller, the switch can be set to Up to 400kHz. dc dc regulator can be generalized using Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Power on Reset, Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. The switching converters's terminals (s) are designed at DUAL. Different dc switching's functions can be applied to 28 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Search for "LTC1438" to find other relevant dc to dc converter ics. Pins number 28 of switching converter in total. Switching converter is a special type of Switching Regulator or Controllers. An input voltage of 3.5V is the minimum required for the dc dc voltage regulator. DC regulator outputs 9V voltage according to the test statistics. At most, the dc to dc regulator accepts 36V input voltage. The dc dc regulator's usual output current is 2A, which should be noted down when you start a project. The Surface Mount makes DC switcher suitable for most applications and prototypes. There is a maximum frequency of 138kHz on this dc regulators.
