UC2572DTR Overview

In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. For outputs of 1, this dc motor controller is suitable. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sVoltages 4.75V~30V are the dc control's supply voltage and operating voltage, respectively. A -40°C~85°C TA dc switcher is not a problem. Using this switching controller, it is possible to switch at 100kHz. The Surface Mount makes it ideal for general dc dc regulator. Switching control is made easier with the dcdc regulator's Current Limit, Ramp. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Switching converters are designed with the terminal (s) at position DUAL . A variety of dc switching's functions can be performed on 8 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 5V. You can find other relevant dc to dc converter ics by searching "UC2572". There are only 8 pins on switching converter. Based on the test statistics, DC regulator outputs voltage -70V. You should note that the dc dc regulator's usual output current is 500mA. The maximum duty cycle of this voltage regulator dc to dc is set to 92 % to ensure reliability during power-up and power-down. It is estimated that this dc regulatorhas a maximum frequency of 300kHz. When running the voltage regulator dc to dc in a circuit, users should apply 30V to ensure safety and reliability. DC switchings that are dormant use 9mA. Users must limit the voltage accordingly because the dc switcher's maximum input voltage is 35V. Voltage 4.2V is necessary for the supply. Output current will not exceed 500mA. Datasheets indicate that the switching converter can output -1V volts at its maximum. -70V voltage output is lower than -70V.
