TPS54290 - TI introduces industry’s first 12-V dual-channel synchronous buck converter with integrated FETs
Texas Instruments today introduced its first dual-output fully synchronous SWIFT power management integrated circuit. The TPS54290 1.5-A/2.5-A converter simplifies power design in consumer electronics with a 12-V power supply, such as a set top box or digital TV.The
Key features and benefits of TPS54290:
· Dual output synchronous buck converter with four integrated MOSFETs provides fully synchronous conversion with 90 percent efficiency, while using 35 percent less board space compared to non-synchronous conversion solutions.
· Current mode control simplifies external compensation, giving the designer greater flexibility when choosing different types of output capacitors.
· 180º out-of-phase operation minimizes ripple current through the input capacitor. Input capacitance is reduced by up to 50 percent, which helps lessen electromagnetic interference.
