High Efficiency Power Supply for Small Size Display
Features
General Description
• Two Outputs:
The APW7252 is boost architecture IC and the major pro-
-+5V (APW7252A)
viding to positive and negative voltage output driven. The
-+5.2V (APW7252B)
APW7252 is synchronize boost IC and also synchronize
• Wide Input Voltage from 2.5V to 5.5V
charge pump output driven. The APW7252 has simply
