Forecasting 35% worth of board-space savings, the TPS54290 SWIFT 12V synchronous dual buck converter supports inputs ranging from 4.5V to 18V and delivers output voltages as low as 0.8V with a 90% efficiency. The device integrates four MOSFETs and operates at a fixed frequency of 300 kHz. Otherwise similar, the TPS54291 and TPS54292 provide switching frequencies of 600 kHz and 1.2 MHz, respectively. Other features include a current mode control that simplifies external compensation and 180º out-of-phase operation to minimize ripple current through the input capacitor. Pricing for the TPS54290/91/92 SWIFT converters is $2.95 each/1,000. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
