KA7553A Overview
Capsuled in the 8-DIP (0.300, 7.62mm) package, the switching controller suits most application needs. For 1 outputs, the dc motor controller is appropriate. A solid enclosure of Tube surrounds pmic. Transistor Driver dc switching's outputs (s) are supported. 8.7V~30V is the supply voltage and the operating voltage of the dc control. A -25°C~85°C TA dc switcher is not a problem. It is suitable for general dc dc regulator when it is set to Through Hole. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. The switching converters's terminal (s) are designed at DUAL . A variety of dc switching's functions can be performed on 8 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. 18V nominal DC switcher's voltage input. A search for "KA7553" will reveal other relevant dc to dc converter ics. There are only 8 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 9.2V. According to the test statistics, DC regulator outputs 16.5V voltage. The dc to dc regulator can only accept 30V input voltage. You should note that the dc dc regulator's usual output current is 1.5A. The maximum duty cycle of this voltage regulator dc to dc is set to 46 % to ensure reliability during power-up and power-down. In most applications and prototype designs, DC switcher is qualified as a Through Hole. 600kHz is the maximum frequency of this dc regulators. As a whole, there are 1 function(s) in the switch converters. There is a possibility that a current higher than 15mA will cause improper operation of the component and possibly damage switching voltage regulators. At 135kHz, this controller performs best.
