The LM706x0 is a family of low-IQ, wide-VIN synchronous buck converters designed for an input voltage range of 4.5V to 65V and delivering up to 10A of output current at fixed output voltages of 3.3V, 5V, 12V, or an adjustable output.
The LM706x0 uses a peak current-mode control architecture for easy loop compensation, fast transient response, and excellent load and line regulation. A pair of LM706x0 converters can be set up in an interleaved mode (paralleled outputs) with accurate current sharing for applications requiring up to 20A of output current.
The LM706x0 features a unique Dual Random Spread Spectrum (DRSS) function that combines low-frequency triangular and high-frequency cycle-by-cycle random modulations for improved EMI performance across a wide range of frequency bands.
Additional features of the LM706x0 include user-selectable diode emulation for lower current consumption at light-load conditions, open-drain Power-Good flag for fault reporting and output monitoring, precision enable input, monotonic start-up into prebiased load, integrated VCC bias supply regulator, internal 2.8ms soft-start time, and thermal shutdown protection with automatic recovery.
The LM706x0 converter comes in a 6mm × 6mm thermally-optimized, 29-pin QFN package. The three die-attach pads (VIN, SW, and PGND) improve thermal performance and board level reliability (BLR).
