PRODUCTION DATA
The spread spectrum function is enabled by a single resistor (37.4 kΩ ±5% or 100 kΩ ±5%) between the MODE pin and the AGND pin or by programming the MODE pin voltage (370mV ±10% or greater than 1.0 V) during initial power up. To switch the spread spectrum function, EN must be grounded for more than 60 μs or VCC must be fully discharged.
