AP1538  
18V 3A 300KHz BUCK CONVERTER  
General Description  
Features  
AP1538 consists of step-down switching regulator with PWM  
control. These devices include a reference voltage source,  
oscillation circuit, error amplifier, internal PMOS.

Input voltage : 3.6V to 18V  
Output voltage : 0.8V to VCC  
Output current : up to 3A  
Duty ratio: 0% to 99% PWM control  
Oscillation frequency: 300KHz typical  
Soft-start like, Current limit and Enable function  
Thermal Shutdown function  
Built-in internal SW P-channel MOS  
SOP-8L and SOP-8L-DEP: Available in “Green”  
Molding Compound (No Br, Sb)  
AP1538 provides low-ripple power, high efficiency, and excellent  
transient characteristics. The PWM control circuit is able to vary  
the duty ratio linearly from 0 up to 99%. This converter also  
contains an error amplifier circuit as well as a soft-start circuit that  
prevents overshoot at startup. An enable function, an over  
current protect function and a short circuit protect function are built  
inside, and when OCP or SCP happens, the operation frequency  
will be reduced from 300KHz to 50KHz. Also, an internal  
compensation block is built in to minimum external component  
count.  
•
Lead Free Finish / RoHS Compliant (Note 1)  
With the addition of an internal P-channel Power MOS, a coil,  
capacitors, and a diode connected externally, these ICs can  
function as step-down switching regulators. They serve as ideal  
power supply units for portable devices when coupled with the  
SOP-8L and SOP-8L-DEP mini-packages, providing such  
outstanding features as low current consumption. Since this  
converter can accommodate an input voltage up to 18V, it is also  
suitable for the operation via an AC adapter.
