LTC1438IG-ADJ#TRPBF Overview
With its 28-SSOP (0.209, 5.30mm Width) package, the switching controller fits the needs of most applications. 2 outputs are supported by the dc motor controller. PMIC packaging is solid with a Tape & Reel (TR) enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). 3.5V~30V is the operating voltage and supply voltage of the dc control. A -40°C~85°C TA dc switcher is not a problem. There is a switch at Up to 400kHz that can be used with this controller. Surface Mount makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Enable, Power on Reset, Soft Start which allows efficient switching control. An analog IC SWITCHING REGULATOR is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. The 28 terminations can be used for a wide range of dc switching. This dc dc converter ic uses a variety of control techniques, including PHASE-SHIFT CONTROL. 15V nominal DC switcher's voltage input. Searching "LTC1438" will return other relevant dc to dc converter ics. Switching converter type is specifically Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 3.5V. Considering the dc to dc regulator can only accept 36V input voltage, it is important to take note of this. It is tested at 9V to determine what the dc controller's highest voltage output is.
