LTC1142HVCG#PBF Overview
The switching controller fits in the 28-SSOP (0.209, 5.30mm Width) package and is ideal for most applications. This dc motor controller can be used to generate outputs with 2 numbers. A solid enclosure of Tube surrounds pmic. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control has a supply voltage and operating voltage of 3.5V~18V. Worked in an dc switcher with a 0°C~70°C TA rating. The switching controller can be switched at Up to 250kHz. The Surface Mount allows it to be used for dc dc regulator in general. Switching control is made easier with the dcdc regulator's Current Limit, Enable. SWITCHING CONTROLLER analog IC connects the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. The 28 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include CONSTANT OFF TIME. DC switcher's input voltageis set to 10V. Searching "LTC1142" will return other relevant dc to dc converter ics. Specially, switching converter corresponds to type Switching Regulator or Controllers. 3.5V should be the minimum input voltage for the dc dc voltage regulator. A value of 0.05A is output as the maximum value of current.
