The EUP3098 is an 8A, 24V high efficiency synchronous step-down regulator. The input voltage range is 4.5V to 24V. Internal low RON HS/LS switches of 28mΩ and 15mΩ provide excellent efficiency over a range of applications, especially for low output voltages and low duty cycles.

The EUP3098 constant-on-time (COT) PWM control method supports high input/output voltage ratios (low duty cycles), and fast transient response while maintaining a near constant operating frequency over line, load and output voltage ranges. So it provides stable operation without complex compensation and even with low ESR ceramic capacitors.

The EUP3098 integrates several protection features to prevent catastrophic switch failure caused by increasing power dissipation. It offer cycle-by-cycle current limit,input under voltage lock-out, internal soft-start,output under voltage protection and over voltage protection and thermal shutdown.

The EUP3098 is available in UQFN2.5×2.5-16 package,operates over the extended (-40°C to +85°C) temperature range.
