FUNCTIONAL DESCRIPTION
increases to ramp up the switch current to bring the
secondary output back to regulation. The output
regulation voltage is determined by the following
relationship:
As shown in the Functional Block Diagram, to
regulate the output voltage in CV (constant voltage)
mode, the ACT365 compares the feedback voltage
at FB pin to the internal reference and generates an
error signal to the pre-amplifier. The error signal,
after filtering out the switching transients and
compensated with the internal compensation
network, modulates the external NPN transistor
peak current at CS pin with current mode PFWM
(Pulse Frequency and Width Modulation) control.
To regulate the output current in CC (constant
current) mode, the oscillator frequency is modulated
by the output voltage.

where RFB1 (R5) and RFB2 (R6) are top and bottom
feedback resistor, NS and NA are numbers of
transformer secondary and auxiliary turns, and VD
is the rectifier diode forward drop voltage at
approximately 0.1A bias.
SW is a driver output that drives the emitter of an
external high voltage NPN transistor. This baseemitter-drive method makes the drive circuit the
most efficient.
Standby (No Load) Mode
In no load standby mode, the ACT365 oscillator
frequency is further reduced to a minimum
frequency while the current pulse is reduced to a
minimum level to minimize standby power. The
actual minimum switching frequency is
programmable with an output preload resistor.
Fast Startup
VDD is the power supply terminal for the ACT365.
During startup, the ACT365 typically draws only
20μA supply current. The startup resistor from the
rectified high voltage DC rail supplies current to the
base of the NPN transistor. This results in an
amplified emitter current to VDD through the SW
pin via Active-Semi's proprietary fast-startup
circuitry until it exceeds the VDDON threshold 19V. At
this point, the ACT365 enters internal startup mode
with the peak current limit ramping up in 10ms.
After switching starts, the output voltage begins to
rise. The VDD bypass capacitor must supply the
ACT365 internal circuitry and the NPN base drive
until the output voltage is high enough to sustain
VDD through the auxiliary winding. The VDDOFF
threshold is 5.5V; therefore, the voltage on the VDD
capacitor must remain above 5.5V while the output
is charging up.
Loop Compensation
The ACT365 integrates loop compensation circuitry
for simplified application design, optimized transient
response, and minimal external components.
Output Cable Resistance Compensation
The ACT365 provides programmable output cable
resistance compensation during constant voltage
regulation, monotonically adding an output voltage
correction up to predetermined percentage at full
power. There are four levels to program the output
cable compensation by connecting a resistor (R10
in Figure 3) from the SW pin to VDD pin. The
percentage at full power is programmable to be 3%,
6%, 9% or 12%, and by using a resistor value of
300k, 150k, 75k or 33k respectively. If there is no
resistor connection, there is no cord compensation.
Constant Voltage (CV) Mode Operation
This feature allows for better output voltage
accuracy by compensating for the output voltage
droop due to the output cable resistance.
In constant voltage operation, the ACT365 captures
the auxiliary flyback signal at FB pin through a
resistor divider network R5 and R6 in Figure 6. The
signal at FB pin is pre-amplified against the internal
reference voltage, and the secondary side output
voltage is extracted based on Active-Semi's
proprietary filter architecture.
Constant Current (CC) Mode Operation
When the secondary output current reaches a level
set by the internal current limiting circuit, the
ACT365 enters current limit condition and causes
the secondary output voltage to drop. As the output
voltage decreases, so does the flyback voltage in a
proportional manner. An internal current shaping
circuitry adjusts the switching frequency based on
the flyback voltage so that the transferred power
remains proportional to the output voltage, resulting
This error signal is then amplified by the internal
error amplifier. When the secondary output voltage
is above regulation, the error amplifier output
voltage decreases to reduce the switch current.
When the secondary output voltage is below
regulation, the error amplifier output voltage

in a constant secondary side output current profile.
The energy transferred to the output during each
switching cycle is ½(LP × ILIM2) × η, where LP is the
transformer primary inductance, ILIM is the primary
peak current, and η is the conversion efficiency.
From this formula, the constant output current can
be derived:

die temperature. The typical over temperature
threshold is 135°C with 20°C hysteresis. When the
die temperature rises above this threshold the
ACT365 is disabled until the die temperature falls
by 20°C, at which point the ACT365 is re-enabled.
TYPICAL APPLICATION
Design Example
(2)
The design example below gives the procedure for
a DCM flyback converter using the ACT365. Refer
to Application Circuit in Figure 3, the design for a
adapter application starts with the following
specification:
where fSW is the switching frequency and VOUTCV is
the nominal secondary output voltage.
The constant current operation typically extends
down to lower than 40% of nominal output voltage
regulation.

The operation for the circuit shown in Figure 3 is as
follows: the rectifier bridge BD1 and the capacitor
C1/C2 convert the AC line voltage to DC. This
voltage supplies the primary winding of the
transformer T1 and the startup resistor R7. The
primary power current path is formed by the
transformer’s primary winding, the NPN transistor,
the ACT365 internal MOSFET and the current
sense resistor R9. The network consisting of
capacitor C4 and diode D6 provides a VDD supply
voltage for ACT365 from the auxiliary winding of the
transformer. C4 is the decoupling capacitor of the
supply voltage and energy storage component for
startup. The diode D8 and the capacitor C5/C6
rectifies and filters the output voltage. The resistor
divider consisting of R5 and R6 programs the
output voltage.
The ACT365 integrates a primary inductor peak
current limit compensation circuit to achieve
constant input power over line and load ranges.
Protection
The ACT365 incorporates multiple protection
functions including over-voltage, over-current and
over-temperature.
Output Short Circuit Protection
When the secondary side output is short circuited,
the ACT365 enters hiccup mode operation. In this
condition, the VDD voltage drops below the VDDOFF
threshold and the auxiliary supply voltage
collapses. This turns off the ACT365 and causes it
to restart. This hiccup behavior continues until the
short circuit is removed.
The minimum and maximum DC input voltages can
be calculated:
Output Over Voltage Protection
The ACT365 includes output over-voltage
protection circuitry, which shuts down the IC when
the output voltage is 40% above the normal
regulation voltage for 4 consecutive switching
cycles. The ACT365 enters hiccup mode when an
output over voltage fault is detected.

PCB Layout Guideline
(9)
Good PCB layout is critical to have optimal
performance. Decoupling capacitor (C4), current
sense resistor (R9) and feedback resistor (R5/R6)
should be placed close to VDD, CS and FB pins
respectively. There are two main power path loops.
One is formed by C1/C2, primary winding, NPN
transistor and the ACT365. The other is the
secondary winding, rectifier D8 and output
capacitors (C5,C6). Keep these loop areas as small
as possible. Connect high current ground returns,

The number of turns of secondary and auxiliary
windings can be derived when Np/Ns=14:
When the transistor is turned off, the voltage on the
transistor’s collector consists of the input voltage
and the reflected voltage from the transformer’s
secondary winding. There is a ringing on the rising
top edge of the flyback voltage due to the leakage
inductance of the transformer. This ringing is
clamped by a RCD network if it is used. Design this
clamped voltage as 50V below the breakdown of
the NPN transistor. The flyback voltage has to be
considered with selection of the maximum reverse
voltage rating of secondary rectifier diode. If a 40V
Schottky diode is used, then the flyback voltage can
be calculated:

VFB Sampling Waveforms
ACT365 senses the output voltage information
through the VFB waveforms. Proper VFB waveforms
are required for IC to operate in a stable status. To
avoid mis-sampling, 1.0µs blanking time is added to
blank the ringing period due to the leakage
inductance and the circuit parasitic capacitance.
Figure 2 is the recommended VFB waveform to
guarantee the correct sampling point so that the
output information can be sent back into the IC to
