LTC1439IG#PBF Overview
As a result of 36-SSOP (0.209, 5.30mm Width) compact design, the switching controller is compatible with most applications. It is sufficient to generate 2 outputs with this dc motor controller. There is a Tube solid enclosure around the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. DC control operates at 3.5V~30V volts and has 3.5V~30V supply voltage. Worked in a -40°C~85°C TA dc switcher before. In this switching controller, the switch can be set to Up to 400kHz. The Surface Mount makes it ideal for general dc dc regulator. Enable, Power on Reset, Soft Start is used for efficient switching control in the dcdc regulator. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. Terminal (s) of the switching converters are designed at the DUAL position. The 36 terminations can be used for a wide range of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. LTC1439 can be searched for other relevant dc to dc converter ics. The switching converter has a total of 36 pins. The type is a particular Switching Regulator or Controllers of switching converter. This dc dc voltage regulator should be powered by a voltage of 3.5V. DC regulator outputs 9V voltage based on test statistics. A starting point for a project is to note down the dc dc regulator's usual output current, which is 2A. This Surface Mount makes DC switcher suitable for most prototypes and applications. The max frequency of the pmic can reach 138kHz.
