GND• Output Voltage Options: Excellent line and load regulation along with high-ADJ (Outputsas Lowas 1.285V) efficiency(> 90%) are featured. Voltage mode control-5.0 (Output Fixedto5V) offers short minimum on-time, allowing the widest ±1.5% Feedback Reference Accuracy ratio between input and output voltages. Internal loop
compensation means that the useris free from the• Switching Frequencyof 500 kHz tedious task of calculating the loop compensation• –40°Cto 125°C Operating Junction Temperature components. Fixed5V output and adjustable outputRange voltage options are available.A switching frequency Precision Enable Pin of 500 kHz allows for small external components and
