LTC3731IG#PBF Product Details
LTC3731IG#PBF Overview
In the 36-SSOP (0.209, 5.30mm Width) package, the switching controller meets most application requirements. 3 outputs are supported by the 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. This dc control operates at 3.8V~7V and has a 3.8V~7V supply voltage. Worked in a -40°C~85°C TA dc switcher before. In this switching controller, the switch can be set to 225kHz~680kHz. The Surface Mount allows it to be used for dc dc regulator in general. Switching control is made easier with the dcdc regulator's Enable, Phase Control, Power Good, Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. The switching converters's terminal (s) are designed at DUAL . The 36 terminations can be used for a wide range of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 5V. LTC3731 can be used to locate other relevant dc to dc converter ics. 36 pins are on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. There is a maximum frequency of 750kHz for this dc regulators. A value of 5A is output as the maximum value of current. There are several dc to dc voltage regulator in the PolyPhase? series. Communication on 1 channels is high-quality.
