LTC1438IG#PBF Overview
In the 28-SSOP (0.209, 5.30mm Width) package, the switching controller meets most application requirements. 2 outputs can be generated with the dc motor controller. PMIC packaging is solid with a Tube enclosure. The system can process Transistor Driver dc switching's outputs (s). A 3.5V~30V voltage is supplied to the dc control and used for operating it. Suitable for working in an dc switcher that has a -40°C~85°C TA. There is a switch at Up to 400kHz that can be used with this controller. The Surface Mount value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Power on Reset, Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. There are a DUAL terminal on the switching converters. A variety of dc switching's functions can be performed on 28 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. It is inputted with a DC switcher's voltage of 15V. LTC1438 can be searched for other relevant dc to dc converter ics. There are 28 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 3.5V. Test statistics indicate DC regulator outputs 5V voltage. The dc to dc regulator can only accept a maximum input voltage of 36V. It is estimated that this dc regulatorhas a maximum frequency of 138kHz. 2A is the greatest value switching converter outputs as current.
