LTC1439CG Overview
In the 36-SSOP (0.209, 5.30mm Width) package, the switching controller meets most application requirements. For outputs of 2, this dc motor controller is suitable. There is a Tube solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) are supported. Voltages 3.5V~30V are the dc control's supply voltage and operating voltage, respectively. Suitable for a 0°C~70°C TA dc switcher. The switching controller is capable of switching at the Up to 400kHz position. It is suitable for general dc dc regulator when it is set to Surface Mount. To provide efficient switching control, Enable, Power on Reset, Soft Start is included in the dcdc regulator. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. switching converters terminal (s) are designed to be at DUAL. An array of 36 terminations of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. LTC1439 can be used to locate other relevant dc to dc converter ics. The type is a particular Switching Regulator or Controllers of switching converter. An input voltage of 3.5V is the minimum required for the dc dc voltage regulator. The dc to dc regulator can only accept 36V input voltage. A value of 2A is output as the maximum value of current.
