AP3105/V/L/R

The AP3105/V/L/R is a low startup current, current g
mode PWM controller with green-mode power-saving g
operation. The PWM switching frequency at normal g
operation is set with 65kHz typically and the dithering g
of frequency will also improve the EMI feature. When g
the load decreases, the frequency will reduce and when at a very low load, the IC will enter the to minimize switching loss.

About 20kHz frequency switching is to avoid the audi- g ble noise as well as reducing the standby loss. The skip g mode point can be adjusted through the external resis- g
tor connected to the current sense resistor.
g The AP3105/V/L/R features a lot of functions such as
the Leading-Edge Blanking LEB of the current sens-
ing, internal slope compensation and several protection
functions including cycle-by-cycle current limit g OCP , VCC Over Voltage Protection VOVP , OTP
and OLP protection. The versatile latch function can be
set by the customer through few components.
g This IC is available in SOT-23-6 package.
