TI Introduces 3-A SWIFT Converter for Digital TV and Industrial Point-of-Load Systems
Texas Instruments Incorporated (TI) (NYSE: TXN) announced a high efficiency, 500-kHz, step-down DC/DC integrated circuit (IC) with integrated FET that delivers 3-A of continuous output current and supports input voltages of 5.5 V to 36 V. The small, simple-to-design switcher speeds time to market for point-of-load systems, such as industrial applications, digital television, DVD, battery charging and 12 V/24 V distributed power systems.
500-kHz Switcher with Integrated FET Device Supports 5.5 V to 36 V Input with 90 Percent Efficiency
TI's non-synchronous TPS5430 SWIFTTM converter provides greater than 90 percent power efficiency and two percent output voltage accuracy (down to 1.23 V). Delivering 3-A of continuous current (4-A peak) at full temperature and operating over a junction temperature range from -40°C to +125°C, the device excels in hot environments where good thermal performance is needed, such as an LCD digital TV display that operates without the use of a cooling fan.
