1 / 7 page AP1605 PWM/PFM DUAL-MODE STEP-DOWN SWITCHING REGULATOR AP1605 Rev. 1 1 of 7 JANUARY 2007 www.diodes.com © Diodes Incorporated • Low current consumption: In operation: 100µA max. Power off: 2µA max. • Input voltage: 2.5V to 7V Adjustable version (+2.5%) • PWM/PFM dual Mode • Oscillation frequency: 300KHz (Typ.) • With a power-off function. • Built-in internal SW P-channel MOS • Lead Free and Green Package: SOP-8L • Lead Free Finish/RoHS Compliant (Note 1) 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. AP1605 provides low-ripple power, high efficiency, and excellent transient characteristics. The PWM/PFM control circuit is able to vary 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. • On-board power supply 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 AP1605 X X X Package Packing - U : Tube -13 : Taping S : SOP-8L Lead-Free L : Lead-Free G : Green Note: 1.
