AP1605  
PWM/PFM Dual-mode Step-Down Switching Regulator  
„ Features  
„ General Description  
- Low current consumption:  
In operation: 100µA max.  
AP1605 consists of CMOS step-down switching  
regulator with PWM/PFM dual mode control. These  
devices include a reference voltage source, oscillation  
circuit, error amplifier, internal PMOS and etc.  
Power off: 2µA max.  
- Input voltage: 2.5V to 7V.  
Adjustable version (+2.5%)  
- PWM/PFM dual Mode  
AP1605 provides low-ripple power, high efficiency,  
- Oscillation frequency: 300KHz (Typ.)  
- With a power-off function.  
- Built-in internal SW P-channel MOS  
- SOP-8L/TSSOP-8L Package.  
and  
excellent  
transient  
characteristics.  
The  
PWM/PFM control circuit is able to very the duty ratio  
linearly 0%~0.25% (PFM) and 25%~100% (PWM).  
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 7V, 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.
