AP3407/A
1.2A, 1.4MHZ HIGH EFFICIENCY SYNCHRONOUS DC-DC BUCK CONVERTER
Description
The AP3407/A is a 1.4MHz fixed frequency, current mode, PWM
synchronous buck (step-down) DC-DC converter, capable of driving a
1.2A load with high efficiency, excellent line and load regulation. The
device integrates synchronous P-channel and N-channel power
MOSFET switches with low on-resistance. It is ideal for powering
portable equipment that runs from a single Li-ion battery.
A standard series of inductors are available from several different
manufacturers optimized for use with the AP3407/A. This feature
greatly simplifies the design of switch-mode power supplies.
The AP3407/A is available in SOT-23-5.

4. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Conditions” is not implied.
Exposure to “Absolute Maximum Ratings” for extended periods may affect device reliability.
5. The junction temperature rise is given by TRISING = PD*θJA, where PD is the power dissipated by regulator, θJA is the thermal resistance from junction of
the die to the ambient temperature; The junction temperature, TJ is given by TJ = TA+TR, where TA is the ambient temperature.
6. DC voltage rating, for short period of spike voltage, the minimum voltage rating is -1V, in 20nS.
