LTC1438CG-ADJ#TRPBF Product Details
LTC1438CG-ADJ#TRPBF Overview
In the 28-SSOP (0.209, 5.30mm Width) package, the switching controller meets most application requirements. The dc motor controller is adquate to generate for 2 outputs. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control has a supply voltage and operating voltage of 3.5V~30V. Qualified to work in an dc switcher with 0°C~70°C TA. This switching controller can switch at Up to 400kHz. The Surface Mount allows it to be used for dc dc regulator in general. To provide efficient switching control, Enable, Power on Reset, Soft Start is included in the dcdc regulator. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminal (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. DC switcher's voltage input is 15V. LTC1438 can be searched for other relevant dc to dc converter ics. In particular, switching converter is a type of Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 3.5V. Voltages 36V are the maximum that the dc to dc regulator will accept. A value of 2A is output as the maximum value of current.
