Texas Instruments rolled out its first dual-output, fully synchronous SWIFT power management IC. 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 device operates from a 4,5 V to 18 V input supply voltage and supports output voltages as low as 0,8 V with a 90% power efficiency rating. The TPS54290 is set at a fixed frequency of 300 kHz; two other family members, the TPS54291 and TPS54292, provide switching frequencies of 600 kHz and 1,2 MHz, further reducing the DC/DC solution size. 180° out-of-phase operation minimises ripple current through the input capacitor. Input capacitance is reduced by up to 50%, which helps lessen electromagnetic interference.
