SG5841J — Highly Integrated Green-Mode PWM
Controller
Features
Description
The highly integrated SG5841/J series of PWM
controllers provides several features to enhance the
performance of flyback converters.
Green-Mode PWM Controller
Low Startup Current : 14µA
Low Operating Current: 4mA
To minimize standby power consumption, a proprietary
green-mode function provides off-time modulation to
continuously decrease the switching frequency at light-
load conditions. This green-mode function enables the
power supply to meet international power conservation
requirements. To further reduce power consumption,
SG5841/J is manufactured using the BiCMOS process.
This allows a low startup current, around 14µA, and an
operating current of only 4mA. As a result, a large
startup resistance can be used.
Programmable PWM Frequency with Hopping
Peak-Current-Mode Control
Cycle-by-Cycle Current Limiting
Synchronized Slope Compensation
Leading-Edge Blanking (LEB)
Constant Output Power Limit
Totem Pole Output with Soft Driving
VDD Over-Voltage Clamping
The built-in synchronized slope compensation achieves
stable peak-current-mode control. The proprietary
internal sawtooth power-limiter ensures a constant
output power limit over a wide range of AC input
Programmable Over-Temperature Protection (OTP)
Internal Open-Loop Protection
voltages, from 90VAC to 264VAC
.
SG5841/J provides many protections. In addition to
cycle-by-cycle current limiting, the internal open-loop
protection circuit ensures safety should an open-loop or
output-short-circuit failure occur. PWM output is
disabled until VDD drops below the UVLO lower limit,
then the controller restarts. An external NTC thermistor
can be applied for over-temperature protection.
VDD Under-Voltage Lockout (UVLO)
GATE Output Maximum Voltage Clamp:18V

Functional Description
Startup Current
Leading-Edge Blanking (LEB)
Typical startup current is only 14µA, which allows a
high-resistance and low-wattage startup resistor to
minimize power loss. For an AC/DC adapter with
universal input range, a 1.5MΩ, 0.25W startup resistor
and a 10µF/25V VDD hold-up capacitor are enough for
this application.
Each time the power MOSFET is switched on, a turn-on
spike occurs at the sense-resistor. To avoid premature
termination of the switching pulse, a leading-edge
blanking time is built in. During this blanking period, the
current-limit comparator is disabled and cannot switch
off the gate drive.
Under-Voltage Lockout (UVLO)
Operating Current
The turn-on and turn-off thresholds are fixed internally
at 16V and 10V. During startup, the hold-up capacitor
must be charged to 16V through the startup resistor to
enable the IC. The hold-up capacitor continues to
supply VDD before the energy can be delivered from
auxiliary winding of the main transformer. VDD must not
drop below 10V during this startup process. This UVLO
hysteresis window ensures that hold-up capacitor is
adequate to supply VDD during startup.
Operating current is around 4mA. The low operating
current enables better efficiency and reduces the
requirement of VDD hold-up capacitance.
Green-Mode Operation
The proprietary green-mode function provides off-time
modulation to continuously decrease the PWM
frequency under light-load conditions. To avoid acoustic
noise problems, the minimum PWM frequency is set
above 22KHz. Green mode dramatically reduces power
consumption under light-load and zero-load conditions.
Power supplies using a SG5841/J controller can meet
restrictive international regulations regarding standby
power consumption.
Gate Output / Soft Driving
The SG5841/J BiCMOS output stage is a fast totem-
pole gate driver. Cross conduction has been avoided to
minimize heat dissipation, increase efficiency, and
enhance reliability. The output driver is clamped by an
internal 18V Zener diode to protect power MOSFET
transistors against undesirable gate over-voltage. A soft
driving waveform is implemented to minimize EMI.
Oscillator Operation
A resistor connected from the RI pin to the GND pin
generates a constant current source for the SG5841/J
controller. This current is used to determine the center
PWM frequency. Increasing the resistance reduces
PWM frequency. Using a 26KΩ resistor, RI, results in a
corresponding 65KHz PWM frequency. The relationship
between RI and the switching frequency is:
Built-in Slope Compensation
The sensed voltage across the current-sense resistor is
used for peak-current-mode control and pulse-by-pulse
current limiting. Built-in slope compensation improves
stability or prevents sub-harmonic oscillation. SG5841/J
inserts a synchronized, positive-going ramp at every
switching cycle.

Constant Output Power Limit
When the SENSE voltage across the sense resistor,
RS, reaches the threshold voltage, around 0.85V, the
output GATE drive is turned off after delay, tPD. This
The range of the PWM oscillation frequency is designed
as 47KHz ~ 109KHz.
SG5841J also integrates a frequency hopping function
internally. The frequency variation ranges from around
62KHz to 68KHz for a center frequency of 65KHz. The
frequency-hopping function helps reduce EMI emission
of a power supply with minimum line filters.
delay introduces additional current, proportional to tPD
•
VIN / LP. The delay is nearly constant, regardless of the
input voltage VIN. Higher input voltage results in larger
additional current and the output power limit is higher
than under low-input line voltage. To compensate this
variation for a wide AC input range, a sawtooth power-
limiter (saw limiter) is designed to solve the unequal
power-limit problem. The saw limiter is designed as a
positive ramp signal (Vlimit_ramp) and fed to the inverting
input of the OCP comparator. This results in a lower
current limit at high-line inputs than at low-line inputs.
Current Sensing / PWM Current Limiting
Peak-current-mode control is utilized in to regulate
output voltage and provide pulse-by-pulse current
limiting. The switch current is detected by a sense
resistor into the SENSE pin. The PWM duty cycle is
determined by this current-sense signal and the
feedback voltage. When the voltage on the SENSE pin
reaches around VCOMP = (VFB–1.0)/3.2, a switch cycle is
terminated immediately. VCOMP is internally clamped to a
variable voltage around 0.85V for output power limit.
VDD Over-Voltage Clamping
VDD over-voltage clamping prevents damage due to
abnormal conditions. If VDD voltage is over the VDD over-
voltage clamping voltage (VDD-CLAMP) and lasts for tD-
VDDCLAMP, the PWM pulses are disabled until the VDD
drops below the VDD over-voltage clamping voltage.

SG5841J • Rev. 1.3.4
www.fairchildsemi.com
10
Thermal Protection
When VDD goes below the turn-off threshold (e.g. 10V)
the controller totally shuts down. VDD is charged up to
the turn-on threshold voltage of 16V through the startup
resistor until PWM output is restarted. This protection
remains activated as long as the overloading condition
persists. This prevents the power supply from
overheating due to overloading conditions.
An NTC thermistor RNTC in series with a resistor RA can
be connected from the RT pin to ground. A constant
current IRT is output from pin RT. The voltage on the RT
pin can be expressed as VRT = IRT × (RNTC + RA), in
which IRT = 2 x (1.3V / RI). At high ambient temperature,
RNTC is smaller, such that VRT decreases. When VRT is
less than 0.62V, the PWM is completely turned off.
Noise Immunity
Limited Power Control
Noise on the current-sense or control signal may cause
significant pulse-width jitter, particularly in the
continuous-conduction mode. Slope compensation
helps alleviate this problem. Good placement and
layout practices should be followed. Avoiding long PCB
traces and component leads, locating compensation
and filter components near SG5841/J, and increasing
power MOS gate resistance improve performance.
The FB voltage increases every time the output of the
power supply is shorted or overloaded. If the FB voltage
remains higher than a built-in threshold for longer than
t
D-OLP, PWM output is turned off. As PWM output is
turned off, the supply voltage VDD begins decreasing.
tD-OLP (ms) = 1.115 × R (KΩ)
