1 / 13 page AME, Inc. 1 AME5110 600mA / 1.2MHz PWM Buck DC-DC Converter Rev. A.03 l High Efficiency “ Extreme Green” l 2.5V to 5.5V Input l Short Circuit Protection l Over-Temperature Shutdown l Under-Volatge Lockout l Superb Transient Response l All AME’ s Lead Free Products Meet RoHS Standards The AME5110 family of Fixed Frequency,High Efficiency, Synchronous Buck, DC-DC Converters, apply the latest innovations in Current-Mode Technology. Available in SOT- 25 package, these devices are typically twice as efficient as standard LDO ’s, making them well suited for most portable applications. The AME5110 is simple to use. As with standard LDO ’s,(1) Input, and (1) Output capacitor are required. The only other element is a small, low cost, 2.2 µH induc- tor. The AME5110 is availabe with fixed output voltages of 1.5V and 1.8V, or adjustable at 600mA. Using a propri- etary “Extreme Green” Technology, battery life is maxi- mized with Frequency Foldback at light Load, and 100% duty when Vin approaches Vout. l Cellular Phones l Digital Cameras l Portable Electronics l USB Devices l MP3 Players l LDO Replacement n General Description n Features n Applications n Typical Application Fixed Voltage Version Adjustable Voltage Version V OUT=VFB (R1+R2)/R2 2.2 µH C IN 4.7 µF CER AME5110 V IN SW V OUT EN GND C OUT 10 µF CER V IN V OUT 2.2 µH C IN 4.7 µF CER AME5110 V IN SW V FB EN GND V IN V OUT R1 R2 22pF C OUT 10 µF CER |
