AME, Inc. 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, 2.2µH 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 VOUT=VFB (R1+R2)/R2 2.2mH CIN 4.7mF CER AME5110 VIN SW VOUTEN GND COUT 10mF CER VIN VOUT 2.2mH CIN 4.7mF CER AME5110 VIN SW VFBEN GND VIN VOUT 22pF COUT 10mF CER

Forcing this pin below 0.3V shuts down the device. In shutdown, all functions are disabled drawing <1µA supply current. Do not leave EN floating. 2 2 GND Ground Pin 3 3 SW Switch Node Connection to Inductor. This pin connects to the drains of the internal main and synchronous power MOSFET switches. 4 4 VIN Main Supply Pin. Must be closely decoupled to GND, Pin2, with a 2.2µF or greater ceramic capactior. N/A 5 VFB Feedback Pin. Receives the feedback voltage from an external resistive divider across the output.
