FUNCTIONAL BLOCK DIAGRAM
FUNCTIONAL DESCRIPTION
ACT2102 skips pulse automatically and thus
achieve very high light load efficiency. With load
increasing, ACT2102 goes into Discontinuous
Current Mode (DCM) and then Continuous Current
Mode (CCM).
As seen in Function Block Diagram, the ACT2102 is
peak current mode controlled synchronous Buck
converter. The converter operates as follows:
A switching cycle starts when the rising edge of the
Oscillator clock output causes the High-Side Power
Switch to turn on and the Low-Side Power Switch to
turn off. With the SW side of the inductor now
connected to IN, the inductor current ramps up to
store energy in the magnetic field. The inductor
current level is measured by the Current Sense
Amplifier and added to the Oscillator ramp signal. If
the resulting summation is higher than the COMP
voltage, the output of the PWM Comparator goes
high. When this happens or when Oscillator clock
output goes low, the High-Side Power Switch turns
off and the Low-Side Power Switch turns on. The
High-Side Power Switch is driven by logic using
HSB as the positive rail. This pin is charged to VSW
+ 5V when the Low-Side Power Switch turns on.
The COMP voltage is the integration of the error
between FB input and the internal 0.923V
reference. If FB is lower than the reference voltage,
COMP tends to go higher to increase current to the
output to keep the output voltage regulated. The
Oscillator normally switches at 310kHz.
Soft Startup
The ACT2102 builds in internal soft startup
function. The internal FB reference voltage rises to
steady state of 0.923V in 2ms to avoid inrush input
current during startup.
Under Voltage Protection (UVP)
At output short circuit or over current, the FB
voltage is usually pulled low. To protect the IC at
over current and short circuit, the ACT2102 builds
in Under Voltage Protection (UVP) function. When
ACT2102 detects the FB voltage below 80% of the
0.923V reference, it pulls low COMP voltage and
discharges internal soft-start capacitor and goes
into hiccup mode. The IC restarts in 32ms after
going into hiccup mode. If the short circuit or over
current is clear, the IC restarts back to normal
mode. The UVP is disabled for 6ms starting from
startup. If the output is short at startup, the output
voltage never rises to nominal voltage. During the
6ms period of time, the output current is limited by
cycle-by-cycle current limit. With 32ms shutdown
period, the average input and output current at
short circuit is significantly reduced and the IC is
more reliable.
Pulse Skipping Mode
To decrease the power recycling at very light load,
the low-side FET current is sensed to emulate a
diode. When the low-side FET current decreases to
zero, the FET is turned off to avoid negative
inductor current. At no load and very light load,

Secondary Over Current Protection
(SOCP)
In normal operation, ACT2102 high-side FET
current is protected by cycle-by-cycle current limit.
In some fault conditions, the input current may run
away. SOCP current limit is set 30% higher than
cycle-by-cycle current limit, and once SOCP is
triggered, ACT2102 goes into hiccup mode and
reduce the power dissipation significantly.
Enable Pin
The ACT2102 has an enable input EN for turning
the IC on or off. The EN pin contains a precision
2.5V comparator with 75mV hysteresis and a 1.3μA
pull-up current source. The comparator can be used
with a resistor divider from VIN to program a startup
voltage higher than the normal UVLO value. If left
floating, the EN pin will be pulled up to roughly 5V
by the internal 1.3μA current source. It can be
driven from standard logic signals greater than
2.5V, or driven with open-drain logic to provide
digital on/off control.
Thermal Shutdown
The ACT2102 disables switching when its junction
temperature exceeds 160°C and resumes when the
temperature has dropped by 30°C.

Output Voltage Setting
Higher inductance reduces the peak-to-peak ripple
current. The trade off for high inductance value is
the increase in inductor core size and series
resistance, and the reduction in current handling
capability. In general, select an inductance value L
based on ripple current requirement:

capacitor, fSW is the switching frequency, L is the
inductor value, and COUT is the output capacitance.
In the case of ceramic output capacitors, RESR is very
small and does not contribute to the ripple.
Therefore, a lower capacitance value can be used
for ceramic type. In the case of tantalum or
electrolytic capacitors, the ripple is dominated by
RESR multiplied by the ripple current. In that case, the
output capacitor is chosen to have sufficiently low
ESR.
External High Voltage Bias Diode
It is recommended that an external High Voltage
Bias diode be added when the system has a 5V
fixed input or the power supply generates a 5V
output. This helps improve the efficiency of the
regulator. The High Voltage Bias diode can be a
low cost one such as IN4148 or BAT54.
Figure 2:
External High Voltage Bias Diode
For ceramic output capacitor, typically choose a
capacitance of about 22µF. For tantalum or
electrolytic capacitors, choose a capacitor with less
than 50mΩ ESR.
Optional Schottky Diode
During the transition between high-side switch and
low-side switch, the body diode of the low-side
power MOSFET conducts the inductor current. The
forward voltage of this body diode is high. An
optional Schottky diode may be paralleled between
the SW pin and GND pin to improve overall
efficiency.
This diode is also recommended for high duty cycle
operation and high output voltage applications.
Input Capacitor
The input capacitor needs to be carefully selected
to maintain sufficiently low ripple at the supply input
of the converter. A low ESR capacitor is highly
recommended. Since large current flows in and out
of this capacitor during switching, its ESR also
affects efficiency.
The input capacitance needs to be higher than
10µF. The best choice is the ceramic type,
however, low ESR tantalum or electrolytic types
may also be used provided that the RMS ripple
current rating is higher than 50% of the output
current. The input capacitor should be placed close
to the IN and GND pins of the IC, with the shortest
traces possible. In the case of tantalum or
electrolytic types, they can be further away if a
small parallel 0.1µF ceramic capacitor is placed
right next to the IC.
Output Capacitor
The output capacitor also needs to have low ESR to
keep low output voltage ripple. The output ripple
voltage is:
VRIPPLE = IOUTMAX K RIPPLE RESR +
VIN
28 × fSW LC OUT

(6)
where IOUTMAX is the maximum output current, KRIPPLE
is the ripple factor, RESR is the ESR of the output

Figure 4 and Figure 5 give two typical car charger
application schematics and associated BOM list.
PC Board Layout Guidance
When laying out the printed circuit board, the
following checklist should be used to ensure proper
operation of the IC.
1) Arrange the power components to reduce both
the AC loop and DC loop size. AC loop includes
input cap, VIN pin and VIN ground pin, DC loop
includes SW pin, inductor, output capacitor and
ground pin.
2) Place input decoupling ceramic capacitor CIN as
close to IN pin as possible. CIN is connected
power GND with vias or short and wide path.
3) Return FB, COMP and ISET to signal GND pin,
and connect the signal GND to power GND at a
single point for best noise immunity.
4) Use copper plane for power GND for best heat
dissipation and noise immunity.
5) Place feedback resistor close to FB pin.
6) Use short trace connecting HSB-CHSB-SW loop
