AP1623  
PWM Control Step-Down Switching Regulator-Converter  
„ Features  
„ General Description  
- Low current consumption:  
In operation: 60µA max.  
AP1623 consists of CMOS step-down switching  
regulator-controllers with PWM control. These devices  
include a reference voltage source, oscillation circuit,  
error amplifier, internal PMOS and etc.  
Power off: 0.5µA max.  
- Input voltage: 2.5V to 16V.  
- Output voltage: 1.8V & Adjustable to 6V.  
- Duty ratio: 0% to 100% PWM control  
- Oscillation frequency: 180KHz typ.  
- Soft-start function: 8ms typ.  
- With a power-off function.  
AP1623 provides low-ripple power, high efficiency,  
and excellent transient characteristics. The PWM  
control circuit is able to very the duty ratio linearly  
from 0 up to 100. This converter also contains an  
error amplifier circuit as well as a soft-start circuit that  
prevent s overshoot at startup.  
- Built-in internal SW P-channel MOS  
- SOP-8L Package.  
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 of up to 16V, it is also  
ideal when operating via an AC adapter.  
„ Applications  
- On-board power supplies of battery devices for  
portable telephones, electronic notebooks, PDA,  
and other hand-held sets.  
- Power supplies for audio equipment, including  
portable CD players and headphone stereo  
equipment.  
- Fixed voltage power supply for cameras, video  
equipment and communications equipment.  
- Power supplies for microcomputers.  
- Conversion from four Ni-H or Ni-Cd cells or two  
lithium-ion cells to 3.3V/3V.  
- Conversion of AC adapter input to 5V/3V.
