Texas Instruments has introduced the TPS84610, a 6V, 6A, low-noise synchronous power module with integrated inductor. The power module is claimed to achieve a 750W/in3 and provide good thermal performance of 12°C/W. It is claimed to simplify telecomms power designs for DSPs and FPGAs by combining the inductor and passives onto a single lead frame. It supports input voltages from 2.95 to 6V, generates a 0.8V output and has an adjustable switching frequency from 500kHz to 2MHz. The power module is available in a 9x11x2.8mm QFN package and meets the EN55022 Class B electromagnetic emissions, making it suitable for use in broadband communications equipment. The power module has high power density at 6A. The company offers four other power modules, including the pin-compatible 2A TPS84210 and 4A TPS84410, which support input voltages from 2.95 to 6V. The 3A TPS84320 and 6A TPS84621 support input voltages from 4.5 to 14.5V and output voltages down to 0.6V. The power modules are designed with the TPS84K, an evaluation module, which includes the 2A synchronous buck evaluation module: TPS84210EVM-002; 3A synchronous buck evaluation module: TPS84320EVM-692; 4A synchronous buck evaluation module: TPS84410EVM-001; 6A synchronous buck evaluation module: TPS84610EVM-003; and 6A synchronous buck evaluation module: TPS84621EVM-692.
