Description
General part information
LM61480-Q1 Series
The LM6x4xx-Q1 buck regulator family are automotive-focused regulators providing either fixed or an adjustable output voltage which can be set from 1 V to 95% of expected input voltage. These regulators operate under a wide input voltage range of 3 to 36V and has transient tolerance up to 42 V.
The family is designed for low EMI. The device incorporates 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.
An open-drainRESEToutput, 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.
