TPS25921LDR Overview


Buck boost converter is part of the package Tape & Reel (TR).A package in the way of 8-SOIC (0.154, 3.90mm Width) is used for voltage regulator.Surface Mount is used to mount this current regulator on the board.As a rule of thumb, the operating temperature should not exceed -40°C~125°C TJ.Current regulator is possible to use a voltage of 4.5V~18V as an input voltage.In the case of 8 terminations, which are the practice of terminating a transmission line with a voltage regulator that has the same characteristic impedance as the line itself, they are fairly common.There are two types of TPS25921s in this family.Computers or other communication constant current regulators have 8 pins, which are pronged contacts.It is mounted by Surface Mount on this current regulator.In order for the constant current to work, it should be powered by a 12VV power source, which is found in most 12VV power supplies.This power converter employs an analog IC called POWER SUPPLY SUPPORT CIRCUIT.In terms of channel number, I would say that it is growing strongly/weakly: 1.There is a maximum voltage to be supplied to 18V by it.The buck boost converter operates with a minimum supply voltage of 4.5V.It reaches 410μA when the operating supply current is supplied for its operation.1.7A's maximal output current results in maximum voltage regulator's design flexibility.With a maximum supply current, 580μA features maximum current regulator's design flexibility.
