TPS40091RHDT Overview
It comes in a 28-VFQFN Exposed Pad package, so switching controller can be used for most applications. This dc motor controller can be used to generate outputs with 4 numbers. PMIC packaging is solid with a Tape & Reel (TR) enclosure. The system can process PWM Signal dc switching's outputs (s). This dc control operates at 4.5V~15V and has a 4.5V~15V supply voltage. Suitable for work in a -40°C~85°C TA dc switcher. Using this switching controller, it is possible to switch at 100kHz~1.2MHz. As it has a Surface Mount value, it can be used for general dc dc regulator. For efficient switching control, the dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. A switching converters's terminal (s) sits at the QUAD position. Various 28 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. Other relevant dc to dc converter ics can be found by searching "TPS40091". Total pins of switching converter are 28. Switching converter is a type of Switching Regulator or Controllers in particular. Statistically, the DC regulator outputs 3.3V voltage. In most cases, the output current of the dc dc regulator will be 120A, so note that when you start the project. DC regulator's maximum frequency is 1MHz. In order to satisfy the need, DC to DC voltage regulator has a value of IT CAN ALSO OPERATE WITH CURRENT MODE. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 15V. As long as the dc switching is in a dormant state, it utilizes 4mA. In order to limit the voltage of a dc switcher whose maximum input voltage is 15V, it must be limited by the user. Voltage 4.5V is necessary for the supply. In this case, the dc switcher won't produce more than 120A watts of output current. As per its datasheet, the switching converter has a maximum output of 3.3V volts. There is 700mV voltage output lower than 700mV on the voltage controller.
