DATA SHEET  
AAT1218  
High Current, 1.2MHz Synchronous Boost Converterr  
Features  
General Description  
•
•
•
•
•
•
•
•
•
The AAT1218 is a general purpose DC/DC synchronous  
boost (step-up) converter providing a tightly regulated  
DC output voltage for continuous output currents up to  
1A (minimum). The maximum peak current in the boost  
switch is limited to a value of 2A (minimum). Operating  
input voltage must be less than the output voltage and  
in the 0.5V to 5.5V range, making the device well suited  
to portable equipment and consumer appliances.  
2.5V to 5.5V Adjustable Output Voltage  
0.5V Minimum Input Voltage  
±2% Output Accuracy  
No Schottky Diode Required (VOUT < 4.5V)  
Up to 95% Efficiency  
400μA Standby Current  
<1μA Shutdown Current  
Integrated Soft-Start Circuitry Limits Inrush Current  
Constant Frequency 1.2MHz Operation  
The boost output voltage is programmed from 2.5V to  
5.5V with an external resistor divider. Optimized internal  
compensation provides fast transient response with no  
external components.  
Inductor Height <1.8mm  
Small Ceramic Capacitors  
Anti-ring Circuit Reduces EMI  
Current Mode Control

•
•
Synchronous rectification eliminates the need for an  
external rectifier for output voltage less than 4.5V. Low  
on-resistance internal switches provide efficiency up to  
95%, which minimizes losses and simplifies packaging  
and circuit board layout. An inductor, two resistors and  
two ceramic output capacitors are all that are required to  
implement a DC/DC boost solution.  
Fast, Stable Transient Response  
No External Compensation  
Cycle-by-Cycle Current Limit

•
Low Inrush Current with 0.7ms Soft-start  
Low Output Ripple: <80mVpp for all Loading Conditions  
(BW = 25MHz)  
•
•
•
Over-Temperature Protection  
The switching frequency is internally set to 1.2MHz to  
minimize external filter size and optimize switching  
losses.  
Adjustable and Fixed Output Versions Available  
Delivers 1A to 5V Output from a Single Cell Li+  
Battery  
•
Integrated soft-start ensures minimal inrush current.  
The “anti-ring” circuit reduces stray EMI during light  
load, discontinuous operation. Input quiescient current is  
less than 400μA at no load.  
Low-profile TDFN33-12 Package  
Applications

DVD Players  
Hard Disk Drive  
MP3 Players  
PDA  
Portable Computers  
Smart Phones  
The device provides cycle-by-cycle current limit and over-  
temperature protection to prevent device over-stress.  
The AAT1218 is available in a Pb-free, 12-pin low profile  
TDFN33 package with rating from -40°C to 85°C.
