DATA SHEET  
AAT1230  
18V, 100mA Step-Up Converter  
General Description  
Features  
The AAT1230/1230-1 is a high frequency, high efficiency  
boost converter capable of 18V maximum output volt-  
age. The internal power switch can deliver 100mA load  
current. It is the ideal power solution to power OLED,  
LCD, and CCD applications operating from a single cell  
lithium-ion battery.  
VIN Range: 2.7V to 5.5V  
Maximum Output: 18V @ 100mA  
True Load Disconnect  
Dynamic Voltage Control Options  
Hysteretic Control  
No External Compensation Components  
Excellent Load Transient Response  
High Efficiency at Light Load  
Hysteretic control provides up to 2MHz switching fre-  
quency and fast response to load transients with small,  
low-cost external components. The fully integrated con-  
trol IC simplifies the design while reducing the total PCB  
footprint. The AAT1230/1230-1 offers a true load discon-  
nect feature which isolates the load from the power  
source when EN/SET is pulled low. This eliminates leak-  
age current and maintains zero voltage at the output  
while disabled.  
Up to 2MHz Switching Frequency  
Ultra-Small Inductor and Capacitors  
Integrated Low RDS(ON) MOSFET Switches  
Up to 85% Efficiency  
<1μA Shutdown Current  
Integrated Soft Start  
Two Turn-On Time Options  
AAT1230: TSS = 0.35ms  
The output voltage can be dynamically set by activating  
one of two reference levels (FB1 or FB2) through the SEL  
logic pin. Optionally, Skyworks' Simple Serial Control™  
(S2Cwire™) single wire interface provides dynamic pro-  
grammability across a wide output voltage range through  
the EN/SET pin.  
AAT1230-1: T = 3.5ms  
SS  
Cycle-by-Cycle Current Limit  
Short-Circuit, Over-Temperature Protection  
Available in TSOPJW-12 or TDFN34-16 Package  
-40°C to +85°C Temperature Range  
The AAT1230/1230-1 are available in a Pb-free, thermal-  
ly-enhanced 16-pin 3x4mm TDFN low-profile package or  
a Pb-free 12-pin TSOPJW package.
