IR1169S
Description
IR1169 is a smart secondary-side driver IC designed to drive N-Channel power MOSFETs used as synchronous
rectifiers in isolated Flyback, Forward or Half-bridge converters. The IC can control one or more paralleled N-
MOSFETs to emulate the behavior of Schottky diode rectifiers. IR1169 works in both DCM and CCM operation
modes. The SYNC pin should be used in CCM mode to directly turn-off the MOSFET by a signal from secondary
or primary controller. The IC is designed to use simple capacitor coupling interface to communicate with primary
controller. In addition to the SYNC control, the drain to source voltage is sensed differentially to determine the
polarity of the current and turn the power switch on and off in proximity of the zero current transition. Ruggedness
and noise immunity are accomplished using an advanced blanking scheme and double-pulse suppression which
allow reliable operation in all operating modes.

Detailed Pin Description
VCC: Power Supply
This is the supply voltage pin of the IC and it is monitored by the under voltage lockout circuit. It is possible to turn
off the IC by pulling this pin below the minimum turn off threshold voltage, without damage to the IC.
To prevent noise problems, a bypass ceramic capacitor connected to Vcc and COM should be placed as close as
possible to the IR1169. This pin is internally clamped.
SYNC: Direct Turn-off and Reset
SYNC is used to directly turn-off the SR MOSFET by an external signal. The gate output of IR1169 is low when
SYNC voltage is higher than VSYHI threshold. The propagation delay from SYNC goes high to gate turns off is
55ns. The turn-off of SYNC is a direct control and it ignores the MOT time (override).
The SYNC pin will reset MOT and Blanking time when SYNC switches from low to high. It will reset MOT timer
and Blanking timer only at the rising edge of signal. This function is useful for very low output voltage condition
(such as overload or short circuit) where the VD voltage is too low to reach Vth3 threshold to reset the timers.
SYNC pin also can be used to control the turn-on time of SR MOSFET (adding additional delay time at turn-on for
noise immunity).
If not used, SYNC pin should be connected to GND.
MOT: Minimum On Time
The MOT programming pin controls the amount of minimum on time. When VSYNC is low and VTH2 is crossed, the
gate signal will become active and turn on the power FET. Spurious ringings and oscillations can trigger the input
comparator off. The MOT blanks the input comparator keeping the FET on for a minimum time.
The MOT is programmed between 200ns and 3us (typ.) by using a resistor referenced to COM.
EN: Enable
This pin is used to activate the IC “sleep” mode by pulling the voltage level below 1.6V (typ). In sleep mode the IC
will consume a minimum amount of current. All switching functions will be disabled and the gate will be inactive.
VD: Drain Voltage Sense
VD is the voltage sense pin for the power MOSFET Drain. This is a high voltage pin and particular care must be
taken in properly routing the connection to the power MOSFET drain.
VS: Source Voltage Sense
VS is the differential sense pin for the power MOSFET Source. This pin should be connected directly to the power
ground pin (7) but must be used to create a kelvin contact as close as possible to the power MOSFET source pin.
GND: Ground
This is ground potential pin of the integrated control circuit. The internal devices and gate driver are referenced to
this point.
VGATE: Gate Drive Output
This is the gate drive output of the IC. Drive voltage is internally limited and provides 1A peak source and 4A peak
sink capability. Although this pin can be directly connected to the power MOSFET gate, the use of minimal gate
resistor is recommended, especially when putting multiple FETs in parallel.
Care must be taken in order to keep the gate loop as short and as small as possible in order to achieve optimal
switching performance.

UVLO/Sleep Mode
The IC remains in the UVLO condition until the voltage on the VCC pin exceeds the VCC turn on threshold
voltage, VCC ON. During the time the IC remains in the UVLO state, the gate drive circuit is inactive and the IC
draws a quiescent current of ICC START. The UVLO mode is accessible from any other state of operation
whenever the IC supply voltage condition of VCC < VCC UVLO occurs.
The sleep mode is initiated by pulling the EN pin below 1.6V (typ). In this mode the IC is essentially shut
down and draws a very low quiescent supply current.
Normal Mode and Synchronized Enable Function
The IC enters in normal operating mode once the UVLO voltage has been exceeded and EN voltage is above
VENHI threshold. When the IC enters Normal Mode from UVLO Mode, the GATE output is disabled (stays low)
until VDS exceeds VTH3 to activate the gate. This ensures that the GATE output is not enabled in the middle of
a switching cycle. This logic prevents any reverse currents across the device due to minimum on time function
in the IC. The gate will continuously drive the SR MOSFET after this one-time activation. The Cycle by Cycle
MOT protection circuit is enabled in Normal Mode.
MOT Protection Mode
If the secondary current conduction time is shorter than the MOT (Minimum On Time) setting, the next driver
output is disabled. This function can avoid reverse current that occurs when the system works at very low
duty-cycles or at very light/no load conditions and reduce system standby power consumption by disabling
GATE outputs. The Cycle by Cycle MOT Check circuit is always activated under Normal Mode and MOT
Protection Mode, so that the IC can automatically resume normal operation once the load increases to a level
and the secondary current conduction time is longer than MOT.

General Description
The IR1169 Smart Rectifier IC can emulate the operation of diode rectifier by properly driving a Synchronous
Rectifier (SR) MOSFET. The direction of the rectified current is sensed by the input comparator using the power
MOSFET RDson as a shunt resistance and the GATE pin of the MOSFET is driven accordingly. Internal blanking
logic is used to prevent spurious transitions. The Synchronous pin (SYNC) can directly take the signal sent from
primary controller to turn off the gate of SR MOSFET prior to the turn-on of primary MOSFET therefore prevent
negative current in SR circuit under CCM condition.
IR1169 is suitable for Flyback, Forward and Resonant Half-Bridge topologies.

Flyback Application
The modes of operation for a Flyback circuit differ mainly for the turn-off phase of the SR switch, while the turn-on
phase of the secondary switch (which corresponds to the turn off of the primary side switch) is identical.
Turn-on phase
When the conduction phase of the SR FET is initiated, current will start flowing through its body diode, generating
a negative VDS voltage across it. The body diode has generally a much higher voltage drop than the one caused by
the MOSFET on resistance and therefore will trigger the turn-on threshold VTH2
.
At that point, if SYNC voltage is low IR1169 will drive the gate of MOSFET on, which will in turn cause the
conduction voltage VDS to drop down. This drop is usually accompanied by some amount of ringing, that can
trigger the input comparator to turn off; hence, a Minimum On Time (MOT) blanking period is used that will
maintain the power MOSFET on for a minimum amount of time.
The programmed MOT will limit also the minimum duty cycle of the SR MOSFET and, as a consequence, the max
duty cycle of the primary side switch.
DCM/CrCM Turn-off phase
Once the SR MOSFET has been turned on, it will remain on until the rectified current will decay to the level where
VDS will cross the turn-off threshold VTH1. This will happen differently depending on the mode of operation.
In DCM the current will cross the threshold with a relatively low dI/dt. Once the threshold is crossed, IR1169 will
turn off gate and the current will start flowing again thru the body diode, causing the VDS voltage to jump negative.
Depending on the amount of residual current, VDS may trigger once again the turn on threshold: for this reason
VTH2 is blanked for a certain amount of time (TBLANK) after VTH1 has been triggered.
The blanking time is internally set. As soon as VDS crosses the positive threshold VTH3 the blanking time is
terminated and the IC is ready for next conduction cycle.

CCM Turn-off phase
In CCM mode the turn on phase is identical to DCM or CrCM and therefore won’t be repeated here.
The turn off transition is much steeper and dI/dt involved is much higher (Figure 6). If the SR controller wait for the
primary switch to turn back on and turn the gate off according to the FET current crossing VTH1, it has high chance
to get reverse current in the SR MOSFET. A predictable turn-off prior to the primary turn-on is necessary. A
decoupling and isolation capacitor can be used to couple the primary gate signal to IR1169 SYNC pin and turn-off
the SR MOSFET prior to the current slope goes to negative. Some turn-on delay to the primary MOSFET can
guarantee no shoot through between the primary and secondary.

IR1169 is designed to directly take the control information from primary side with capacitor coupling. A high
voltage, low capacitance capacitor is used to send the primary gate driver signal to the SYNC pin. To have the
circuit work properly, a Y cap is required between primary ground and secondary ground. No pulse transformer is
required for the SYNC function, helps saving cost and PCB area.
The turn-off phase with SYNC control is shown in Figure 8.
In this case a blanking period is not applied; SYNC logic high will reset blanking time.
