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.  
Programmable deadtime (Turn-on  
Delay) Between Activation of Each

Programmable Limits for Both  
Transformer Volt- Second Product  
and PWM Duty Cycle  
The oscillator is programmed with two resistors and a capacitor to set  
switching frequency and maximum duty cycle. A separate synchronized  
ramp provides a voltage feedforward pulse width modulation and a pro-  
grammed maximum volt-second limit. The generated clock from the oscilla-  
tor contains both frequency and maximum duty cycle information.

CLK can be used to synchronized up to five other  
UCC3580 PWMs.

sourcing up to 0.5A and sinking 1A.  
DELAY: A resistor from DELAY to GND programs the

PGND to GND at a single point so that no high frequency  
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,
