AP384XG
General Description
Features
The AP384XG is a Green Mode PWM controller. It is
specially designed for off-line AC-DC adapter and bat-
tery charger applications where both needs for low
standby power and high efficiency in normal operation
are required. In a well designed product, the AP384XG
is capable to allow the system consuming only 0.5W
power in standby mode.
·
Green Mode PWM Controller to Support the
"Blue Angel" Norm
·
·
·
·
·
·
·
Adjustable Skip Cycle Mode Operation
Low Start-up Current: 50μA (Typ.)
Low Standby Operating Current: 6mA
Internal Leading Edge Blanking
Adjustable Oscillator Frequency up to 500KHz
Totem Pole Output
In normal operation, the AP384XG features adjustable
frequency by using an external resistor and capacitor
Under Voltage Lock Out (UVLO)
combination. When output power falls below a given · Over-Temperature Protection
level, the IC automatically switches to the skip mode,
which works by skipping switching cycles. The
AP384XG also features low start-up and low standby
operating current for its special topology.
·

Applications
The AP384XG provides accurate protection against
over-temperature, over-current and maximal output
power.

Figure 4. Basic Test Circuit
Figure 4 is the basic test circuit for AP384XG. In testing, the high peak currents associated with capacitive loads
necessitate careful grounding techniques. Timing and bypass capacitors should be connected close to pin 5 in a
single point ground. The transistor and 5k potentiometer are used to sample the oscillator waveform and apply an
adjustable ramp to pin 3.
