LTC1929CG-PG#PBF Overview


Capsuled in the 28-SSOP (0.209, 5.30mm Width) package, the switching controller can be used for a wide range of applications. It is sufficient to generate 2 outputs with this dc motor controller. There is a Tube solid enclosure around the pmic. The system can process Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4V~36V. Qualified to work in a 0°C~85°C TA dc switcher. As it has a Surface Mount value, it can be used for general dc dc regulator. DCDC regulator is controlled efficiently by Enable, Power Good, Soft Start. The switch converters are connected to a SWITCHING CONTROLLER analog IC. The switching converters's terminal (s) are designed at DUAL . 28 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. LTC1929 can be searched for other relevant dc to dc converter ics. There are only 28 pins on switching converter. Input voltage of dc dc voltage regulator must be 4V. The dc to dc regulator can only accept 36V input voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 3kA. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 99 %. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. DC regulator360kHz has the maximum frequency. The frequency at which this controller can perform well is 300kHz.
