AAT1210
High Power DC/DC Boost Converter
with Optional Dynamic Voltage Programming
General Description
Features
The AAT1210 is a high power DC/DC boost (step-up)
converter with an input voltage range from 2.7 to 5.5V.
The output voltage can be set from VIN + 0.5V to 18V.
The total solution is less than 1mm in height. High oper-
ating efficiency makes the AAT1210 the ideal solution for
battery powered and consumer applications.
The step-up converter operates at frequencies up to
2MHz, enabling ultra-small external filtering compo-
nents. Hysteretic current mode control provides excel-
lent transient response with no external compensation,
achieving stability across a wide operating range with
minimal design effort.
The AAT1210 true load disconnect feature extends bat-
tery life by isolating the load from the power source
when the EN/SET pin is pulled low, ensuring zero volts
output during the disable state. This feature eliminates
the external boost converter leakage path and achieves
standby quiescient current <1μA without an external
switching device.
A fixed output voltage is set using two external resistors.
Alternatively, the output may be adjusted dynamically
across a 2.0x range. The output can toggle between two
preset voltages using the SEL logic pin. Optionally, the
output can be dynamically set to any one of 16 pro-
grammed levels using Skyworks' patented Simple Serial
Control™ (S2Cwire™) interface.
The AAT1210 is available in a Pb-free, thermally-
enhanced 16-pin 3x4mm TDFN low-profile package and
is rated over the -40°C to +85°C temperature range.

Function
Switched power input. Connect to the power inductor.
Feedback pin for high output voltage set point. Pin set to 1.2V when SEL is high and disabled when SEL is
low. Disabled with S2Cwire control. Tie directly to FB2 pin for static (xed) output voltage.
Feedback pin for low output voltage set point. Pin set to 0.6V when SEL is low and disabled when SEL is
high. Voltage is set from 0.6V to 1.2V with S2Cwire control. Tie directly to FB1 pin for static (xed) output
voltage.
Ground pin.
Power ground for the boost converter; connected to the source of the N-channel MOSFET. Connect to the
input and output capacitor return.
Boost converter switching node. Connect the power inductor between this pin and the LIN pin.
No connection.
Input voltage for the converter. Connect this pin directly to the VP pin.
Logic high selects FB1 high output reference. Logic low selects FB2 low output reference. Pull low for
S2Cwire control.
Active high enable pin. Alternately, input pin for S2Cwire control using the FB2 reference.
Input power pin; connected internally to the source of the P-channel MOSFET. Connect externally to the
input capacitor(s).
Exposed paddle (bottom). Connected internally to the SW pins. Can be tied to bottom side PCB heat sink
to optimize thermal performance.
