IR3843AMTR1PBF Product Details
IR3843AMTR1PBF Overview
optimized performance is achieved by utilizing the Tape & Reel (TR) package in this voltage regulator. Throughout this voltage regulator, there are 15 terminations. There are two types of analog ICs in this voltage regulator 12v: SWITCHING REGULATOR ICs, which are the ones used in older voltage regulator 12vs. The space-saving 15-PowerVQFN package is available for this voltage regulator. The voltage regulator 12v has 1 outputs. The adjusting voltage regulator generates Adjustable output. As the name implies, this voltage regulator 12v is designed for mounting on a Surface Mount bracket. During switching regulator operation, the operating temperature should remain at -40°C~125°C TJ. This voltage regulator 12v reaches a switching frequency of 225kHz~1.32MHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 1.5V. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.7V. There is a maximum input voltage of 21V for this voltage regulator 12v. A regulator voltage's peak reflow temperature amounts to 260 being indestructible. The voltage regulator 12v is designed to provide a nominal input voltage of 12V for operation. In the particular voltage regulators, the IR3843AMPBF family is represented. A voltage of 18.9V volts can be generated by DC DC switching regulator. There are 15 pins used for switching regulator operation. For this switching regulator, we recommend keeping the output voltage at at least 700mV volts. A 3A A maximum output current is required to meet the switching regulator operation requirements. With a maximum output voltage of 18.9V, DC DC switching regulator has a very high efficiency. In the SupIRBuck® family, this part palys an important role in DC DC switching regulator's traget applications. With 5.5V as the supply voltage, this DC-DC switching regulator will operate.
