The LM6x4xx family of buck regulators are regulators that provide either fixed or adjustable output voltage that can be set from 1 V to 95% of expected input voltage. These regulators operate under a wide input voltage range or 3 V to 36 V and have transient tolerance up to 42 V.

The family is designed for low EMI. The devices incorporate pin-selectable spread spectrum and an adjustable SW node rise time. Dual Random Spread Spectrum (DRSS) frequency hopping is set to ±5.5% (typical), drastically reducing peak emissions through a combination of triangular and pseudo random modulation. DRSS also includes advanced techniques to reduce output voltage ripple caused by spread spectrum modulation.

An open-drain RESET output with filtering and delayed release 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 5 µA (typical). Electrical characteristics are specified over a junction temperature range of –40°C to +150°C.
