LTC1929IG-PG#PBF Overview


It comes in a 28-SSOP (0.209, 5.30mm Width) package, so switching controller can be used for most applications. For 2 outputs, the dc motor controller is appropriate. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) are supported. 4V~36V is the operating voltage and supply voltage of the dc control. Suitable for working in an dc switcher that has a -40°C~85°C TA. It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Enable, Power Good, Soft Start. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Switching converters are designed with the terminal (s) at position DUAL . Different dc switching's functions can be applied to 28 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Search for "LTC1929" to find other relevant dc to dc converter ics. There are only 28 pins on switching converter. dc dc voltage regulators should have a minimum input voltage of 4V. It should be fully noted that the dc to dc regulator only accepts 36V input voltage at most. In most cases, the dc dc regulator's output current is 3kA. This information should be noted when you begin working with the component. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. DC regulator has a maximum frequency of 360kHz. The frequency at which this controller can perform well is 300kHz.
