Description：

The AP8232 series is a CMOS step-up

switching regulator which mainly consists of a

reference voltage source, an oscillation circuit,

an error amplifier, a phase compensation circuit,

a PWM/PFM switching control circuit. With an

external low-ON-resistance Nch Power MOS,

this product is applicable to applications

requiring high efficiency and high output current.

The AP8232 series switches its operation to the

PFM control circuit whose duty ratio is 15 % with

to the PWM/PFM switching control circuit under

a light load and to prevent decline in the

efficiency by IC operation current.

Feature：

 Low voltage operation: Start-up is guaranteed from

0.9 V(IOUT =1 mA )

 Duty ratio: Built-in PWM/PFM switching control

circuit 15 to 78 % .

 oscillator frequency：300KHz

 External parts: coil, diode, capacitor, and transistor

 Output voltage range: 1.5V ~6.5 V

 Output voltage accuracy：±2%

 Soft start function: 2 ms.

PACKAGE：SOT-23-5

Typical Application:

 Mobile phones (PDC, GSM, CDMA, IMT200 etc.)

 Bluetooth equipment

 PDA

 Portable communication modem

 Portable games

 Cameras

 Digital cameras

 Cordless phones

 Notebook computers
