functions required in the construction of a
regulating power supply, inverter, or switching
regulator on a single chip. They also can be used
as the control element for high-power-output
applications. The SG2524 and SG3524 were
designed for switching regulators of either polarity, transformer-coupled dc-to-dc converters, transformerless
voltage doublers, and polarity-converter applications employing fixed-frequency, pulse-width modulation
(PWM) techniques. The complementary output allows either single-ended or push-pull application. Each device
includes an on-chip regulator, error amplifier, programmable oscillator, pulse-steering flip-flop, two uncommitted
pass transistors, a high-gain comparator, and current-limiting and shutdown circuitry.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to network ground terminal.
2. The reference regulator may be bypassed for operation from a fixed 5-V supply by connecting the VCC and reference output
(REF OUT) pin both to the supply voltage. In this configuration, the maximum supply voltage is 6 V.
3. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operation at the absolute maximum TJ of 150°C can impact reliability.
4. The package thermal impedance is calculated in accordance with JESD 51-7.

SLVS077D – APRIL 1977 – REVISED FEBRUARY 2003
PRINCIPLES OF OPERATION†
The SG2524 is a fixed-frequency pulse-width-modulation (PWM) voltage-regulator control circuit. The regulator
operates at a fixed frequency that is programmed by one timing resistor, RT, and one timing capacitor, CT. RT
establishes a constant charging current for CT. This results in a linear voltage ramp at CT, which is fed to the
comparator, providing linear control of the output pulse duration (width) by the error amplifier. The SG2524 contains
an onboard 5-V regulator that serves as a reference, as well as supplying the SG2524 internal regulator control
circuitry. The internal reference voltage is divided externally by a resistor ladder network to provide a reference within
the common-mode range of the error amplifier as shown in Figure 6, or an external reference can be used. The output
is sensed by a second resistor divider network and the error signal is amplified. This voltage is then compared to the
linear voltage ramp at CT. The resulting modulated pulse out of the high-gain comparator then is steered to the
appropriate output pass transistor (Q1 or Q2) by the pulse-steering flip-flop, which is synchronously toggled by the
oscillator output. The oscillator output pulse also serves as a blanking pulse to ensure both outputs are never on
simultaneously during the transition times. The duration of the blanking pulse is controlled by the value of CT. The
outputs may be applied in a push-pull configuration in which their frequency is one-half that of the base oscillator, or
paralleled for single-ended applications in which the frequency is equal to that of the oscillator. The output of the error
amplifier shares a common input to the comparator with the current-limiting and shut-down circuitry and can be
overridden by signals from either of these inputs. This common point is pinned out externally via the COMP pin, which
can be employed to either control the gain of the error amplifier or to compensate it. In addition, the COMP pin can
be used to provide additional control to the regulator.
APPLICATION INFORMATION†
oscillator
The oscillator controls the frequency of the SG2524 and is programmed by RT and CT as shown in Figure 4.
f [
1.30
R C
T T
where: RT is in kΩ
CT is in µF
f is in kHz
Practical values of CT fall between 0.001 µF and 0.1 µF. Practical values of RT fall between 1.8 kΩ and 100 kΩ.
This results in a frequency range typically from 130 Hz to 722 kHz.
blanking
The output pulse of the oscillator is used as a blanking pulse at the output. This pulse duration is controlled by
the value of CT as shown in Figure 5. If small values of CT are required, the oscillator output pulse duration can
be maintained by applying a shunt capacitance from OSC OUT to ground.
synchronous operation
When an external clock is desired, a clock pulse of approximately 3 V can be applied directly to the oscillator
output terminal. The impedance to ground at this point is approximately 2 kΩ. In this configuration, RTCT must
be selected for a clock period slightly greater than that of the external clock.
† Throughout these discussions, references to the SG2524 apply also to the SG3524.

SLVS077D – APRIL 1977 – REVISED FEBRUARY 2003
APPLICATION INFORMATION†
synchronous operation (continued)
If two or more SG2524 regulators are operated synchronously, all oscillator output terminals must be tied
together. The oscillator programmed for the minimum clock period is the master from which all the other
SG2524s operate. In this application, the CTRT values of the slaved regulators must be set for a period
approximately 10% longer than that of the master regulator. In addition, CT (master) = 2 CT (slave) to ensure
that the master output pulse, which occurs first, has a longer pulse duration and, subsequently, resets the slave
regulators.
voltage reference
The 5-V internal reference can be employed by use of an external resistor divider network to establish a
reference common-mode voltage range (1.8 V to 3.4 V) within the error amplifiers (see Figure 6), or an external
reference can be applied directly to the error amplifier. For operation from a fixed 5-V supply, the internal
reference can be bypassed by applying the input voltage to both the VCC and VREF terminals. In this
configuration, however, the input voltage is limited to a maximum of 6 V.

error amplifier
The error amplifier is a differential-input transconductance amplifier. The output is available for dc gain control
or ac phase compensation. The compensation node (COMP) is a high-impedance node (RL = 5 MΩ). The gain
of the amplifier is AV = (0.002 Ω–1)RL and easily can be reduced from a nominal 10,000 by an external shunt
resistance from COMP to ground. Refer to Figure 3 for data.
compensation
COMP, as previously discussed, is made available for compensation. Since most output filters introduce one
or more additional poles at frequencies below 200 Hz, which is the pole of the uncompensated amplifier,
introduction of a zero to cancel one of the output filter poles is desirable. This can be accomplished best with
a series RC circuit from COMP to ground in the range of 50 kΩ and 0.001 µF. Other frequencies can be canceled
by use of the formula f ≈ 1/RC.

APPLICATION INFORMATION†
shutdown circuitry
COMP also can be employed to introduce external control of the SG2524. Any circuit that can sink 200 µA can
pull the compensation terminal to ground and, thus, disable the SG2524.
In addition to constant-current limiting, CURR LIM+ and CURR LIM– also can be used in transformer-coupled
circuits to sense primary current and shorten an output pulse should transformer saturation occur. CURR LIM–
also can be grounded to convert CURR LIM+ into an additional shutdown terminal.
current limiting
A current-limiting sense amplifier is provided in the SG2524. The current-limiting sense amplifier exhibits a
threshold of 200 mV ±25 mV and must be applied in the ground line since the voltage range of the inputs is limited
to 1 V to –1 V. Caution should be taken to ensure the –1-V limit is not exceeded by either input, otherwise,
damage to the device may result.
Foldback current limiting can be provided with the network shown in Figure 7. The current-limit schematic is
shown in Figure 8.

output circuitry
The SG2524 contains two identical npn transistors, the collectors and emitters of which are uncommitted. Each
transistor has antisaturation circuitry that limits the current through that transistor to a maximum of 100 mA for
fast response.
general
There are a wide variety of output configurations possible when considering the application of the SG2524 as
a voltage-regulator control circuit. They can be segregated into three basic categories:
D Capacitor-diode-coupled voltage multipliers
D Inductor-capacitor-implemented single-ended circuits
D Transformer-coupled circuits
Examples of these categories are shown in Figures 9, 10, and 11, respectively. Detailed diagrams of specific
applications are shown in Figures 12–15.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
