Texas Instruments TPS54618 monolithic synchronous switcher

Texas Instruments has released a 6 A converter, claimed to be the industry’s smallest and most efficient.

The TPS54618 monolithic synchronous switcher with two integrated 12 mΩ FETs, provides 95% efficiency and low operating current to 2.95 to 6 V point-of-load designs used in DSP- and FPGA-based communications, test and medical equipment.

The device is 30% smaller than other 6 A devices. The integrated converter provides high performance and reliability, including current mode control, which provides simple external compensation and flexible component selection, especially small ceramic capacitors.

The scalable converter is pin compatible with other low-current SWIFT synchronous buck converters, such as the 3 A, 2 MHz TPS54318.

Features include: wide switching frequency range (200 kHz to 2 MHz) combines high efficiency with design flexibility; synchronised switching frequency from a master clock eliminates beat noise in sensitive data acquisition circuitry.
