AP1533  
PWM CONTROL 1.8A STEP-DOWN CONVERTER  
General Description  
Features  
AP1533 consists of step-down switching regulator with PWM  
control. These devices include a reference voltage source,  
oscillation circuit, error amplifier, internal PMOS.

Input voltage: 4V to 23V  
Output voltage: 0.8V to VCC  
Output current: 1.8A up to peak 2A  
Duty ratio: 0% to 99% PWM control  
Oscillation frequency: 300KHz typ.  
Soft-start like, Current limit and Enable function  
Thermal Shutdown function  
Built-in internal SW P-channel MOS  
SOP-8L: Available in “Green” Molding Compound  
(No Br, Sb)  
AP1533 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 mini-package, providing such outstanding features as low  
current consumption. Since this converter can accommodate an  
input voltage up to 23V, it is also suitable for the operation via an  
AC adapter.
