UC2845BD1R2G Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. This dc motor controller can be used to generate outputs with 1 numbers. Tape & Reel (TR) solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 7.6V~30V and has a 7.6V~30V supply voltage. Qualified to work in a -25°C~85°C TA dc switcher. It can switch at 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. Switching control is made easier with the dcdc regulator's Frequency Control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. Various 8 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. A search for "UC284*B" will reveal other relevant dc to dc converter ics. Pins number 8 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. Statistically, DC regulator outputs 5V volts. It's important to remember that the dc dc regulator's normaloutput current is 1A, so you should note it down when starting a new project. Voltage regulator dc to dc is designed to operate at 48 % duty cycle during power-ups and power-downs to ensure reliability. This Surface Mount makes DC switcher suitable for most prototypes and applications. Switching controllers work at 52kHz Hz. In the presence of a current greater than 17mA, the component may fail to operate properly and may be damaged.
