Texas Instruments LM6x4xx/LM6x4xx-Q1 Buck Converters are regulators providing either fixed or an adjustable output voltage which can be set from 1V to 95% of the expected input voltage. These regulators operate under a wide input voltage range of 3V to 36V and have transient tolerance up to 42V. The family is designed for low EMI. The device incorporates a pin selectable spread spectrum and an adjustable SW node rise time. Dual Random Spread Spectrum (DRSS) frequency hopping is set to ±4% (typical), drastically reducing peak emissions through a combination of triangular and pseudorandom modulation, and includes advanced techniques to reduce output voltage ripple caused by spread spectrum modulation.
The Texas Instruments LM6x4xx/LM6x4xx-Q1 has an open-drain RESET output, with filtering and delayed-release, and gives a true indication of system status. In auto mode, the device automatically transitions between Fixed frequency Pulse Width Modulation (FPWM) and Pulse Frequency Modulation (PFM) modes of operation, allowing an unloaded current consumption of only 5µA (typical). Electrical characteristics are specified over a junction temperature range of –40°C to +150°C. The LM6x4xx-Q1 devices are AEC-Q100 qualified for automotive applications.
