Single Ended Active Clamp/Reset PWM
FEATURES
DESCRIPTION
Provides Auxiliary Switch Activation
Complementary to Main Power
Switch Drive
The UCC3580 family of PWM controllers is designed to implement a variety
of active clamp/reset and synchronous rectifier switching converter topolo-
gies. While containing all the necessary functions for fixed frequency, high
performance pulse width modulation, the additional feature of this design is
the inclusion of an auxiliary switch driver which complements the main
power switch, and with a programmable deadtime or delay between each
transition. The active clamp/reset technique allows operation of single
ended converters beyond 50% duty cycle while reducing voltage stresses
on the switches, and allows a greater flux swing for the power transformer.
This approach also allows a reduction in switching losses by recovering en-
ergy stored in parasitic elements such as leakage inductance and switch
capacitance.

UCC3580 PWMs.

components of the output switching currents are in the
ground plane on the circuit board.
as follows:
Delay 1= 1.1pF ·R3
Delay2 is designed to be larger than Delay1 by a ratio
shown in Figure 2.
RAMP: A resistor (R4) from RAMP to the input voltage
and a capacitor (CR) from RAMP to GND programs the
feedforward ramp signal. RAMP is discharged to GND
when CLK is high and allowed to charge when CLK is
low. RAMP is the line feedforward sawtooth signal for the
PWM comparator. Assuming the input voltage is much
greater than 3.3V, the ramp is very linear. A flux
comparator compares the ramp signal to 3.3V to limit the
maximum allowable volt-second product:
EAIN: Inverting input to the error amplifier. The
noninverting input of the error amplifier is internally set to
2.5V. EAIN is used for feedback and loop compensation.
EAOUT: Output of the error amplifier and input to the
PWM comparator. Loop compensation components
connect from EAOUT to EAIN.
GND: Signal Ground.
LINE: Hysteretic comparator input. Thresholds are 5.0V
and 4.5V. Used to sense input line voltage and turn off
OUT1 when the line is low.
Volt-Second Product Clamp = 3.3 • R4 • CR.
REF: Precision 5.0V reference pin. REF can supply up to
5mA to external circuits. REF is off until VDD exceeds 9V
(–1 and –3 versions) or activates the 15V clamp (–2 and
–4 versions) and turns off again when VDD droops below
8.5V. Bypass REF to GND with a 1mF capacitor.
OSC1 & OSC2: Oscillator programming pins. A resistor
connects each pin to a timing capacitor. The resistor
connected to OSC1 sets maximum on time. The resistor
connected to OSC2 controls guaranteed off time. The
combined total sets frequency with the timing capacitor.
Frequency and maximum duty cycle are approximately
given by:
SHTDWN: Comparator input to stop the chip. The
threshold is 0.5V. When the chip is stopped, OUT1 is low
and OUT2 continues to oscillate with guaranteed off time
equal to two non-overlap delay times. OUT2 continues to
switch after SHTDWN is asserted until the voltage on
VDD falls below VCS (typically 4 V) in order to discharge
the clamp capacitor.

UVLO and Startup
this clamp must be activated as an indication of reaching
the UVLO on threshold. The internal reference (REF) is
brought up when the UVLO on threshold is crossed. The
startup logic ensures that LINE and REF are above and
SHTDWN is below their respective thresholds before
outputs are asserted. LINE input is useful for monitoring
actual input voltage and shutting off the IC if it falls be-
low a programmed value. A resistive divider should be
used to connect the input voltage to the LINE input. This
feature can protect the power supply from excessive
currents at low line voltages.
For self biased off-line applications, -2 and -4 versions
(UVLO on and off thresholds of 15V and 8.5V typical)
are recommended. For all other applications, -1 and -3
versions provide the lower on threshold of 9V. The IC re-
quires a low startup current of only 160mA when VDD is
under the UVLO threshold, enabling use of a large trickle
charge resistor (with corresponding low power dissipa-
tion) from the input voltage. VDD has an internal clamp
at 15V which can sink up to 10mA. Measures should be
taken not to exceed this current. For -2 and -4 versions,

APPLICATION INFORMATION (cont.)
The soft start pin provides an effective means to start
the IC in a controlled manner. An internal current of
20 A begins charging a capacitor connected to SS once
the startup conditions listed above have been met. The
voltage on SS effectively controls maximum duty cycle
on OUT1 during the charging period. OUT2 is also con-
trolled during this period (see Figure 1). Negation of any
of the startup conditions causes SS to be immediately
discharged. Internal circuitry ensures full discharge of
SS (to 0.3V) before allowing charging to begin again,
provided all the startup conditions are again met.

Voltage Feedforward and Volt-Second Clamp
UCC3580 has a provision for input voltage feedforward.
As shown in Figure 3, the ramp slope is made propor-
tional to input line voltage by converting it into a charging
current for CR. This provides a first order cancellation of
the effects of line voltage changes on converter perfor-
mance. The maximum volt-second clamp is provided to
protect against transient saturation of the transformer
core. It terminates the OUT1 pulse when the RAMP volt-
age exceeds 3.3V. If the feedforward feature is not used,
the ramp can be generated by tying R4 to REF. How-
ever, the linearity of ramp suffers and in this case the
maximum volt-second clamp is no longer available.

APPLICATION INFORMATION (cont.)
Output Configurations
a single pin is used to program the delays between
OUT1 and OUT2 on both sets of edges. Figure 1 shows
the relationships between the outputs. Figure 2 gives the
ratio between the two delays. During the transition from
main to auxiliary switch, the delay is not very critical for
ZVS turn-on. For the first half of OUT1 off-time, the body
diode of the auxiliary switch conducts and OUT2 can be
turned on any time. The transition from auxiliary to main
switch is more critical. Energy stored in the parasitic in-
ductance(s) at the end of the OUT2 pulse is used to dis-
charge the parasitic capacitance across the main switch
during the delay time. The delay (Delay 1) should be op-
timally programmed at 1/4 the resonant period deter-
mined by parasitic capacitance and the resonant
inductor (transformer leakage and/or magnetizing induc-
tances, depending on the topology). However, depend-
ing on other circuit parasitics, the resonant behavior can
change, and in some cases, ZVS turn-on may not be ob-
tainable. It can be shown that the optimum delay time is
independent of operating conditions for a specific circuit
and should be determined specifically for each circuit.
The UCC3580 family of ICs is designed to provide con-
trol functions for single ended active clamp circuits. For
different implementations of the active clamp approach,
different drive waveforms for the two switches (main and
auxiliary) are required. The -3 and -4 versions of the IC
supply complementary non-overlapping waveforms
(OUT1 and OUT2) with programmable delay which can
be used to drive the main and auxiliary switches. Most
active clamp configurations will require one of these out-
puts to be transformer coupled to drive a floating switch
(e.g. Figure 5). The -1 and -2 versions have the phase of
OUT2 inverted to give overlapping waveforms. This con-
figuration is suitable for capacity coupled driving of a
ground referenced p-channel auxiliary switch with the
OUT2 drive while OUT1 is directly driving an n-channel
main switch (e.g. Figure 4).
The programmable delay can be judiciously used to get
zero voltage turn-on of both the main and auxiliary
switches in the active clamp circuits. For the UCC3580,

retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
