Operation and Application
ACT4515 is a wide input voltage, high efficiency Active
CC step-down DC-DC converter that operates in either
CV (Constant Output Voltage) mode or CC (Constant
Output Current) mode. ACT4515 provides up to 1.5A
output current at 210kHz switching frequency. Active
CC is a patent-pending control scheme to provide
Figure 1:

CC function accuracy by sensorless constant current control, which eliminates the expensive, high accuracy current sense resistor, making it ideal for battery
charging applications. charging applications. The
ACT4515 operates at constant output voltage mode until
it reaches the CC limit set by the ISET resistor. The devices are available in a SOP-8 package.
Key Component Selection
Higher output inductance reduces the inductor peak
-to-peak current at the expense of higher larger core size
and inductance DCR value. Usually, an optimum inductance value is selected to make its peak-to-peak current
20%-30% of the maximum load current. The Schottky
diode must have current rating higher than the maximum
output current and the reverse voltage rating higher than
the maximum input voltage. Output capacitor is selected
to keep the peak-to-peak voltage ripple under required
value and also meet the load transient requirements. For
this application, 22uFx2 ceramic capacitors are needed.
In the case of tantalum or electrolytic types, 220uF capacitor is connected in parallel with a small 1ìF-10uF
ceramic capacitor to achieve small output voltage ripple
and meet the requirements of input and load dynamic
response.

Lp is the transformer inductance value, Rcs is the
current sense resistor, which is shown as R4 in
the schematic. Fsw is the switching frequency,
which design value is 45kHz. ŋ is the overall system efficiency, which value is approximately
equal to 70%. Voutcc is the output voltage, which
setting is through the flyback voltage of auxiliary
winding and the feedback resistor R8, R9 as
shown in formula (2).
Operation and Application
Figure 1 is the schematic of an offline charger
using ACT361 to provide output power of
5V1000mA. This circuit is a typical flyback power
supply which includes the AC rectified circuit (D1D4,C1, L1, L2, C2),power drive circuit (BD pin,
Q1), secondary rectified circuit (D7, C6) and the
IC control circuit. ACT361 is a Primary Side
Regulator (PSR) so that the power supply unit
can regulate current and voltage without Optocoupler. Pin 4 and Pin 2 are the VDD and ground
pins to provide power for the IC. Pin 3 is the base
drive for the NPN transistor. Pin 1 is the switching
pin. Pin 5 is the feedback pin that senses the output current and output voltage. Pin 6 is the peak
current sense pin. Resistance of R7 determines
the output DC cord compensation percentage.
This circuit can be used as universal charger for
Cell Phones, PDAs, MP3,Portable Media Players, DSCs, and Other Portable Devices and Appliances.

using ACT366YH to provide output power of
12V1000mA. This circuit is a typical flyback
power supply which includes the AC rectified circuit (BD1,C1, C2),power drive circuit (BD pin,
Q1), secondary rectified circuit (D8, C5,C6) and
the IC control circuit. ACT366YH is a Primary
Side Regulator (PSR) so that the power supply
unit can regulate current and voltage without
Opto-coupler. Pin 6 and Pin 2,4,7 are the VDD
and ground pins to provide power for the IC. Pin
8 is the base drive for the NPN transistor. Pin 1 is
the switching pin. Pin 5 is the feedback pin that
senses the output current and output voltage. Pin
3 is the peak current sense pin. Resistance of
R10 determines the output DC cord compensation percentage. This circuit can be used as universal
charger
for

can provide drivers for one (min), or two (max) LED
lights in series due to the wide VDD operation
ranges.
Key Component Selection
The turn ratio of the primary turn and the secondary
turn (NP/NS), together with the R7 sets the
maximum output current value as shown in formula
(1.1). The voltage setting is through the flyback
voltage of auxiliary winding and the feedback
resistor R5, R6 as shown in formula (1.2).
NP/NS/NAUX (160/10/23) must be designed correctly
to make sure it operates in DCM mode and it can
supply either one to two LEDs in same circuit. A
design value VOUTCV equal to 3.5V and IOUTCC-MIN
equal to 350mA are used to do the design.
Operation and Application
Figure 1 is the schematic of an offline LED driver
using ACT364 to provide a power output of 3.5V,
350mA. This circuit is a typical flyback type power
supply which includes the AC rectified circuit (BD1,
C1), power drive circuit (BD pin, Q1), secondary
rectified circuit (D3, C4) and the IC(ACT364) control
circuit. ACT364 is a Primary Side Regulator (PSR)
so that the power supply unit can regulate current
and voltage without opto-coupler. Pin 4 and Pin 2
are the VDD and ground pins to provide power for
the IC. Pin 3 is the base driver for the NPN
transistor. Pin 1 is the switching pin. Pin 5 is the
feedback pin that senses the output current and
output voltage. Pin 6 is the peak current sense pin.

drivers for one (min), or two (max) LED lights in
series due to the wide VDD operation ranges.
Key Component Selection
The turn ratio of the primary turn and the secondary
turn (NP/NS), together with the R7 sets the
maximum output current value as shown in formula
(1.1). The voltage setting is through the flyback
voltage of auxiliary winding and the feedback
resistor R5, R6 as shown in formula (1.2). NP/NAUX
(160/23) must be designed correctly to make sure it
operates in DCM mode and it can supply either one
to two LEDs in same circuit. A design value VOUTCV
equal to 3.5V and IOUTCC-MIN equal to 350mA are
used to do the design.
Operation and Application
Figure 1 is the schematic of an offline LED driver
using ACT364 to provide a power output of 3.5V,
350mA. This circuit is tapped buck power supply
which includes the AC rectified circuit (BD1, C1),
power drive circuit (BD pin, Q1), secondary rectified
circuit (D3, C4) and the IC(ACT364) control circuit.
ACT364 is a Primary Side Regulator (PSR) so that
the power supply unit can regulate current and
voltage without opto-coupler. Pin 4 and Pin 2 are
the VDD and ground pins to provide power for the
IC. Pin 3 is the base driver for the NPN transistor.
Pin 1 is the switching pin. Pin 5 is the feedback pin
that senses the output current and output voltage.
Pin 6 is the peak current sense pin. Through a
patented PSR technology, this circuit can provide

Operation and Application
Figure 1 is the schematic of an offline LED driver
using ACT364 to provide a power output of 12V,
350mA. This circuit is a typical flyback type power
supply which includes the AC rectified circuit (BD1,
C1, L1), primary snubber circuit (D1, R1, C2),
power drive circuit (BD pin, Q1), secondary rectified
circuit (D3, C4) and the IC control circuit. ACT364 is
a Primary Side Regulator (PSR) so that the power
supply unit can regulate current and voltage without
Opto-coupler. Pin 4 and Pin 2 are the VDD and
ground pins to provide power for the IC. Pin 3 is the
base drive for the NPN transistor. Pin 1 is the
switching pin. Pin 5 is the feedback pin that senses
the output current and output voltage. Pin 6 is the
The turn ratio of the primary turn and the secondary
turn (NP/NS), together with the R7 sets the
maximum output current value as shown in formula
(1.1). The voltage setting is through the flyback
voltage of auxiliary winding and the feedback
resistor R5, R6 as shown in formula (1.2).
NP/NS/NAUX (160/20/24) must be designed correctly
to make sure it operates in DCM mode and it can
supply either two or three LEDs in same circuit. A
design value VOUTCV equal to 12V and IOUTCC MIN
equal to 300mA are used to do the design.
