PRODUCTION DATA
Hiccup mode protection is enabled by a single resistor (37.4 kΩ ±5% or 62.0 kΩ ±5%) between the MODE pin and the AGND pin or by programming the MODE pin voltage (370 mV ±10% or 620 mV ±10%) during initial power up. To switch the hiccup mode protection function, EN must be grounded for more than 60 μs or VCC must be fully discharged.
