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
