The output voltage range is limited by Vin. (Vout Vin 2 Vdc) 2. The ripple & noise are measured with 47 F + 47 F + 0.1 F capacitor at 20 MHz BW. 3. SYNC frequency must be greater than operating frequency, externally tie SYNC to GND if synchronization functionality not required. 4. All specifications valid at nominal input voltage, full load and +25 C after warm-up time unless otherwise stated. 5. The product information and specifications are subject to change without prior notice. 2 www.eaton.com/electronics
