3 Description
The LM708x0-Q1 is a family of low-IQ, wide-VIN
synchronous buck converters designed for an input
voltage range of 4.5V to 80V and delivering up to 8A
of output current at fixed output voltages of 3.3V, 5V,
12V, or an adjustable output.
The LM708x0-Q1 uses a peak current-mode control
architecture for easy loop compensation, fast transient
response, and excellent load and line regulation. A
pair of LM708x0-Q1 converters can be set up in an
interleaved mode (paralleled outputs) with accurate
current sharing for applications requiring up to 16A of
output current.
The LM708x0-Q1 features a unique Dual Random
Spread Spectrum (DRSS) function that combines
low-frequency triangular and high-frequency cycleby-
cycle random modulations for improved EMI
performance across a wide range of frequency bands.
