LTC1438CG#TRPBF Overview


Capsuled in the 28-SSOP (0.209, 5.30mm Width) package, the switching controller can be used for a wide range of applications. It is sufficient to generate 2 outputs with this dc motor controller. A solid enclosure of Tape & Reel (TR) surrounds pmic. With Transistor Driver dc switching's output (s), it is able to handle it. DC control operates at 3.5V~30V volts and has 3.5V~30V supply voltage. Work well in dc switchers with a 0°C~70°C TA. In this switching controller, the switch can be set to Up to 400kHz. dc dc regulator can be generalized using Surface Mount. Enable, Power on Reset, Soft Start provides dcdc regulator efficient switching control. An analog IC with the SWITCHING REGULATOR signal is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . A variety of dc switching's functions can be performed on 28 terminations. The control methods that these dc dc converter ics use include PHASE-SHIFT CONTROL. A DC switcher's nominal voltage of 15V is input. Other relevant dc to dc converter ics will be returned if you search "LTC1438". Specially, switching converter corresponds to type Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 3.5V. DC regulator outputs 3.3V voltage according to the test statistics. Considering the dc to dc regulator can only accept 36V input voltage, it is important to take note of this. The value of DC to DC voltage regulator is set at ALSO HAS OUTPUT OF 5V in order to fulfill the requirements more effectively.
