NEW PRODUCT
The AP3776 is a high performance AC/DC power supply controller for
battery charger and adapter applications. It can meet less than 10mW
standby power for “Super Star” charger criteria. The device uses
Pulse Frequency Modulation (PFM) method to build discontinuous
conduction mode (DCM) flyback power supplies.
(Top View)
The AP3776 provides accurate constant voltage (CV), constant
current (CC) and outstanding dynamic performance without requiring
an opto-coupler. It also eliminates the need of loop compensation
circuitry while maintaining stability.

Figure 2. The Operation Waveform of Flyback PSR System
For primary-side regulation, the primary current ip(t) is sensed by a current sense resistor RCS (R5,R6 as shown in Typical Application of
AP3776).The current rises up linearly at a rate of:
dip (t ) Vin (t )

dt
LM
(1)
As illustrated in Figure 2, when the current ip(t) rises up to IPK, the switch Q1 turns off. The constant peak current is given by:
I PK 
VCS
RCS
(2)
The energy stored in the magnetizing inductance LM each cycle is therefore:
Eg 
1
2
 LM  I PK
2
(3)
So the power transferring from the input to the output is given by:
P
1
2
 LM  I PK  f SW
2
(4)
Where, the fSW is the switching frequency. When the peak current IPK is constant, the output power depends on the switching frequency f SW.
The maximum frequency for AP3776 system is about 84kHz.
Constant Voltage Operation
As to constant-voltage (CV) operation mode, the AP3776 detects the auxiliary winding voltage at FB pin to regulate the output voltage. The
auxiliary winding voltage is coupled with secondary side winding voltage, so the auxiliary winding voltage at secondary rectification diode D1
conduction time is:
V AUX 
N AUX
 VOUT  Vd 

(5)
Where the Vd is the diode forward voltage drop.

Figure 3. Auxiliary Voltage Waveform
The voltage detection point is at 2/3 of the D1 on-time. The voltage detection point is changed with the different primary peak current. The CV
loop control function of AP3776 then generates a D1 off-time to regulate the output voltage.
Constant Current Operation
The AP3776 can work in constant-current (CC) mode. Figure 2 shows the secondary current waveforms.
In CC operation mode, the CC control loop of AP3776 will keep a fixed proportion between D1 on-time Tons and D1 off-time Toffs. The fixed
proportion is
Tons 4

Toffs 4
(6)
The relationship between the output current and secondary peak current I PKS is given by:
1
Tons
I OUT   I PKS 
2
Tons  Toffs
(7)
As to tight coupled primary and secondary winding, the secondary peak current is
I PKS 

 I PK

(8)
Thus the output constant-current is given by:
I OUT 
1 NP
Tons
2 N

 I PK 

2 NS
Tons  Toffs 8 N S
(9)
Therefore, AP3776 can realize CC mode operation by constant primary peak current and fixed diode conduction duty cycle.
Multiple Segment Constant Peak Current
As to the original PFM PSR system, the switching frequency decreases with output current decreasing, which will encounter audible noise issue
since switching frequency decrease to audio frequency range, about less than 20kHz.
In order to avoid audible noise issue, AP3776 uses 3-segment constant primary peak current control method. At constant voltage mode, the
current sense threshold voltage is multiple segments with different loading, as shown in Figure 4, which are VCS_H for high load, VCS_M for
medium load and VCS_L for light load. At constant current mode, the peak current is still V CS_H. As to no load and ultra light load condition (LL
mode), the current reference is also VCS_L. But the LL mode operating is different, which will be described in next section.
It can be seen from the following Figure 4 that with multiple segment peak current control, AP3776 power system can keep switching frequency
above 24kHz from light load to heavy load and guarantee the audible noise free performance.

3.
The LL Mode Operating (Typical Application with APR343)
At no load and light load, the AP3776 works in Low Light mode (LL mode) and the output voltage is detected by APR343. In order to achieve
ultra low standby power in LL mode, the static current (ICC_NL) of the AP3776 is reduced from 280μA to 100μA.
• The conditions of exiting LL mode---VCPC>65mV or tOFF<tDELAY+30μs
• The conditions of entering LL mode---VCPC<33mV and tOFF≥tDELAY+30μs
In LL mode, when the APR343 detects the output voltage is lower than its trigger voltage, the APR343 VDET pin emits a periodical pulse
current. This pulse current will generate a pulse voltage on feedback winding through the transformer coupling. When the AP3776 detects this
VPULSE (>100mV is valid), primary switch immediately turns on to provide one energy pulse to supply output terminal and primary VCC. To
achieve low standby power, the lower switching frequency is necessary. But if the off time is too long, the VCC voltage will reduce to very low
level. To avoid VCC being lower than VOPR(Min), a minimum switching frequency is specified by the APR343 (tDIS). If VOUT does not fall below
trigger voltage during tDIS, APR343 VDET pin will emit the periodical pulse current and let the primary switch turn on.
4.
Leading Edge Blanking
When the power switch is turned on, a turn-on spike will occur on the sense-resistor. To avoid false-termination of the switching pulse, a 500ns
leading-edge blanking (from power MOSFET on) is built in. During this blanking period, the current sense comparator is disabled and the gate
driver can’t be switched off.
5.
Adjustable Line Compensation
Since there is a constant delay time from the CS pin voltage reaching the given VCS reference to the power MOSFET turning off, the real
primary peak current value always has a gap with the ideal value. The gap value changes with different input line voltage, which is caused by
different current rising slope, results in different system constant current value.
In order to eliminate the constant current deviation due to line voltage, the adjustable line compensation is introduced to AP3776 design. By
sensing the negative voltage of FB pin which is linear to the line voltage, a current (ILINE) proportional to line voltage flows out from the CS pin to
the resistor RLINE, and create an adjustable compensation voltage to clear up the primary current gap, so that the excellent line regulation of
output current will be achieved.

Fixed Cable Compensation
As we know, CPC voltage reflects the power system loading percentage. By introducing a rising voltage, which is linear to CPC voltage, to the
FB reference voltage, AP3776 can realize the fixed cable compensation to match the voltage drop at output cable. The cable compensation is
7% (typ).
Protection
1. FB Over Voltage Protection (OVP)
When the voltage of FB pin exceeds VFB(OVP) at Tons period, AP3776 immediately shuts down for tOFF(MAX) and then detects the FB voltage
again to see if VFB(OVP) condition is removed. The VCC voltage will drop during the tOFF(MAX). When VCC is still higher than VOPR(Min) after
tOFF(MAX), and VFB(OVP) condition is removed, the IC will enter normal operating mode; but if VFB(OVP) condition is not removed, AP3776 will
remain shut down and wait for another tOFF(MAX). When VCC drops to VOPR(Min) during the tOFF(MAX), AP3776 will enter the restart mode, and
VCC voltage changes between VTH(ST) and VOPR(Min) until VFB(OVP) condition is removed.
2.
Open Circuit Protection (OCKP)
If the down resistance of FB pin short or up resistance open, there will be no voltage on FB pin, so the sample signal can’t be monitored, and
the OCKP protection will be triggered. The protection operating process is the same as over voltage protection process.
3.
Short Circuit Protection (SCP)
Short Circuit Protection (SCP) detection principle is similar to the normal output voltage feedback detection by sensing FB pin voltage. When
the detected FB pin voltage is below VFB(SCP) for a duration of about tOFF(MAX), the SCP is triggered. Then the AP3776 enters hiccup mode
that the IC immediately shuts down and then restarts, so that the VCC voltage changes between VTH(ST) and VOPR(Min) until VFB(SCP)
condition is removed.
As to the normal system startup, the time duration of FB pin voltage below VFB(SCP) should be less than tOFF(MAX) to avoid entering SCP
mode. But for the output short condition or the output voltage below a certain level, the SCP mode should happen.
Figure 6 shows the AP3776 normal start-up waveform. If the voltage of FB pin reaches above VFB(SCP) during tOFF(MAX) after VCC gets to the
VTH(ST), the IC doesn’t enter the SCP mode. Figure 7 shows that VOUT is short and the voltage of FB pin is lower than VFB(SCP) during
tOFF(MAX), then the AP3776 triggers the SCP and enters the hiccup mode.

RCS Short Protection
When the primary side current sense resistance is shorted, the primary side current rapidly increases, and the transformer saturates, which leads
to some components’ damage. The AP3776 draws in the RCS short protection to avoid the damage. If the voltage of CS pin is smaller than 0.15V
at the primary side maximum on time tonp(MAX), the RCS short protection is triggered, and the AP3776 immediately shuts down, and then
restarts.
5.
Over Temperature Protection (OTP)
When the IC junction temperature exceeds the thermal shutdown temperature threshold of +130ºC, the device shuts down immediately. Retry is
allowed if junction temperature reduces by hysteresis temperature value.
