FEATURES
GENERAL DESCRIPTION
• Few external components required
The TDA8358J is a power circuit for use in 90° and 110°
colour deflection systems for 25 to 200 Hz field
frequencies, and for 4 : 3 and 16 : 9 picture tubes. The IC
contains a vertical deflection output circuit, operating as a
high efficiency class G system. The full bridge output
circuit allows DC coupling of the deflection coil in
combination with single positive supply voltages.
• High efficiency fully DC coupled vertical bridge output
circuit
• Vertical flyback switch with short rise and fall times
• Built-in guard circuit
• Thermal protection circuit
• Improved EMC performance due to differential inputs
The east-west output stage is able to supply the sink
current for a diode modulator circuit.
• East-west output stage.
The IC is constructed in a Low Voltage DMOS (LVDMOS)
process that combines bipolar, CMOS and DMOS
devices. DMOS transistors are used in the output stage
because of absence of second breakdown.

compensation input
The vertical driver circuit has a bridge configuration.
The deflection coil is connected between the
complimentary driven output amplifiers. The differential
input circuit is voltage driven. The input circuit is specially
designed for direct connection to driver circuits delivering
a differential signal but it is also suitable for single-ended
applications. The output currents of the driver device are
converted to voltages by the conversion resistors
RCV1 and RCV2 (see Fig.3) connected to pins INA
and INB. The differential input voltage is compared with
the voltage across the measuring resistor RM, providing
internal feedback information. The voltage across RM is
proportional with the output current. The relationship
between the differential input current and the output
current is defined by:
2 × Ii(dif)(p-p) × RCV = Io(p-p) × RM
The output current should measure 0.5 to 3.2 A (p-p) and
is determined by the value of RM and RCV. The allowable
input voltage range is 100 mV to 1.6 V for each input. The
formula given does not include internal bondwire
resistances. Depending on the value of RM and the internal
bondwire resistance (typical value 50 mΩ) the actual value
of the current in the deflection coil will be about 5% lower
than calculated.

Flyback supply
The flyback voltage is determined by the flyback supply
voltage VFB. The principle of two supply voltages (class G)
allows to use an optimum supply voltage VP for scan and
an optimum flyback supply voltage VFB for flyback, thus
very high efficiency is achieved. The available flyback
output voltage across the coil is almost equal to VFB, due
to the absence of a coupling capacitor which is not
required in a bridge configuration. The very short
rise and fall times of the flyback switch are determined
mainly by the slew-rate value of more than 300 V/µs.

Protection
MGL867
The output circuit contains protection circuits for:
• Too high die temperature
The die has been glued to the metal block of the package. If the metal
block is not insulated from the heatsink, the heatsink shall only be
connected directly to pin VGND.
• Overvoltage of output A.

For that purpose a compensation resistor RCMP is
connected between pins OUTA and COMP. The value of
RCMP is calculated by:
Guard circuit
A guard circuit with output pin GUARD is provided.
The guard circuit generates a HIGH-level during the
flyback period. The guard circuit is also activated for one
of the following conditions:
( V FB – V loss ( FB ) – V P ) × R D1 × ( R S + 300 )
R CMP = ------------------------------------------------------------------------------------------------------------( V FB – V loss ( FB ) – I coil ( peak ) × R coil ) × R M
• During thermal protection (Tj ≈ 170 °C)
where:
• During an open-loop condition.
• Rcoil is the coil resistance
• Vloss(FB) is the voltage loss between pins VFB and OUTA
at flyback.
The guard signal can be used for blanking the picture tube
and signalling fault conditions. The vertical
synchronization pulses of the guard signal can be used by
an On Screen Display (OSD) microcontroller.
East-west amplifier
The east-west amplifier is a current driver sinking the
current of a diode modulator circuit. A feedback
resistor REWF (see Fig.4) has to be connected between
the input and output of the inverting east-west amplifier in
order to convert the east-west correction input current into
an output voltage. The output voltage of the east-west
circuit at pin OUTEW is given by:
Damping resistor compensation
HF loop stability is achieved by connecting a damping
resistor RD1 (see Fig.4) across the deflection coil.
The current values in RD1 during scan and flyback are
significantly different. Both the resistor current and the
deflection coil current flow into measuring resistor RM,
resulting in a too low deflection coil current at the start of
the scan.
Vo ≈ Ii × REWF + Vi
The maximum output voltage is Vo(max) = 68 V, while the
maximum output current of the circuit is Io(max) = 750 mA.
The difference in the damping resistor current values
during scan and flyback have to be externally
compensated in order to achieve a short settling time.

Notes
1. To limit VOUTA to 68 V, VFB must be 66 V due to the voltage drop of the internal flyback diode between pins OUTA
and VFB at the first part of the flyback.
2. Allowable input range for both inputs: VI(bias) + Vi(dif)(peak) < 1600 mV and VI(bias) − Vi(dif)(peak) > 100 mV.
3. This value specifies the sum of the voltage losses of the internal current paths between pins VP and OUTA, and
between pins OUTB and GND. Specified for Tj = 125 °C. The temperature coefficient for Vloss(1) is a positive value.
4. This value specifies the sum of the voltage losses of the internal current paths between pins VP and OUTB, and
between pins OUTA and GND. Specified for Tj = 125 °C. The temperature coefficient for Vloss(2) is a positive value.
5. The linearity error is measured for a linear input signal without S-correction and is based on the ‘on screen’
measurement principle. This method is defined as follows. The output signal is divided in 22 successive equal time
parts. The 1st and 22nd parts are ignored, and the remaining 20 parts form 10 successive blocks k. A block consists
of two successive parts. The voltage amplitudes are measured across RM, starting at k = 1 and ending at k = 10,
where Vk and Vk+1 are the measured voltages of two successive blocks. Vmin, Vmax and Vavg are the minimum,
maximum and average voltages respectively. The linearity errors are defined as:
Vk – Vk + 1
a) LE = -------------------------- × 100% (adjacent blocks)
V avg
V max – V min
b) LE = ------------------------------- × 100% (non adjacent blocks)
V avg

10. VP(ripple) = 500 mV (RMS value); 50 Hz < fP(ripple) < 1 kHz; measured across RM.
11. This value specifies the internal voltage loss of the current path between pins VFB and OUTA.
12. This value specifies the internal voltage loss of the current path between pins OUTEW and EWGND.
13. Measured for REWF = 10 kΩ; REWL = 30 Ω; Vo = 6 V.

Full bridge vertical deflection output circuit
in LVDMOS with east-west amplifier
The flyback supply voltage calculated this way is about
5% to 10% higher than required.
Supply voltage calculation
For calculating the minimum required supply voltage,
several specific application parameter values have to be
known. These parameters are the required
maximum (peak) deflection coil current Icoil(peak), the coil
parameters Rcoil and Lcoil, and the measuring resistance
of RM. The required maximum (peak) deflection coil
current should also include the overscan.
Calculation of the power dissipation of the vertical
output stage
The power dissipation of the vertical output stage is given
by the formula:
PV = Psup − PL
The deflection coil resistance has to be multiplied with 1.2
in order to take account of hot conditions.
The power to be supplied is given by the formula:
I coil ( peak )
P sup = V P × ----------------------- + V P × 0.015 [A] + 0.3 [W]
2
Chapter “Characteristics” supplies values for the voltage
losses of the vertical output stage. For the first part of the
scan the voltage loss is given by Vloss(1). For the second
part of the scan the voltage loss is given by Vloss(2).
In this formula 0.3 [W] represents the average value of the
losses in the flyback supply.
The voltage drop across the deflection coil during scan is
determined by the coil impedance. For the first part of the
scan the inductive contribution and the ohmic contribution
to the total coil voltage drop are of opposite sign, while for
the second part of the scan the inductive part and the
ohmic part have the same sign.
The average external load power dissipation in the
deflection coil and the measuring resistor is given by the
formula:
2
( I coil ( peak ) )
P L = -------------------------------- × ( R coil + R M )
3
For the vertical frequency the maximum frequency
occurring must be applied to the calculations.
Example
The required power supply voltage VP for the first part of
the scan is given by:
Table 1
The required power supply voltage VP for the second part
of the scan is given by:
V P ( 2 ) = I coil ( peak ) × ( R coil + R M )
+ L coil × 2I coil ( peak ) × f vert ( max ) + V loss ( 2 )
The minimum required supply voltage VP shall be the
highest of the two values VP(1) and VP(2). Spread in supply
voltage and component values also has to be taken into
account.

Product specification
Full bridge vertical deflection output circuit
in LVDMOS with east-west amplifier
TDA8358J
Power dissipation calculation for the east-west stage
The required heatsink thermal resistance is given by:
In general the shape of the east-west output wave form is
a parabola. The output voltage will be higher at the
beginning and end of the vertical scan compared to the
voltage at the scan middle, while the output current will be
higher at the scan middle. This results in an almost uniform
power dissipation distribution during scan. Therefore the
power dissipation can be calculated by multiplying the
average values of the output voltage and the output
current of pin OUTEW.
T j – T amb
R th ( h – a ) = ------------------------ – ( R th ( j – c ) + R th ( c – h ) )
P EW + P V
When we use the values known we find:
130 – 40
R th ( h – a ) = ---------------------- – ( 4 + 1 ) = 5 K/W
3+6
The heatsink temperature will be:
Th = Tamb + Rth(h-a) × Ptot = 40 + 5 × 9 = 85 °C
When verifying the dissipation also the start-up and stop
dissipation should be taken into account. Power
dissipation during start-up can be 3 to 5 times higher than
during normal operation.
Equivalent thermal resistance network
The TDA8358J has two independent power dissipating
systems, the vertical output circuit and the east-west
circuit.
Heatsink calculation
It is recommended to verify the individual maximum (peak)
junction temperatures of both circuits. Therefore the
maximum (peak) power dissipations of the circuits and
also the heatsink temperature should be measured.
The maximum (peak) junction temperatures can be
calculated by using an equivalent thermal network
(see Fig.5).
The value of the heatsink can be calculated in a standard
way with a method based on average temperatures.
The required thermal resistance of the heatsink is
determined by the maximum die temperature of 150 °C.
In general we recommend to design for an average die
temperature not exceeding 130 °C. It should be noted
that the heatsink thermal resistance Rth(h-a) found by
performing a standard calculation will be lower then
normally found for a vertical deflection stand alone device,
due to the contribution of the EW power dissipation to this
value.
The network does only consist the contribution of the
maximum (peak) power dissipation PTRv(peak), being the
dissipation of the most critical transistor internally
connected to pins OUTB and VGND. The model assumes
equivalent maximum (peak) power dissipations during the
different vertical scan stages for all the functionally paired
transistors. The calculated maximum (peak) junction
temperatures should not exceed Tj = 150 °C.
EXAMPLE
Measured or known values:
PEW = 3 W; PV = 6 W; Tamb = 40 °C; Tj = 130 °C;
Rth(j-c) = 4 K/W; Rth(c-h) = 1 K/W.

The total contact time of successive solder waves must not
exceed 5 seconds.
SOLDERING
Introduction to soldering through-hole mount
packages
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (Tstg(max)). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
This text gives a brief insight to wave, dip and manual
soldering. A more in-depth account of soldering ICs can be
found in our “Data Handbook IC26; Integrated Circuit
Packages” (document order number 9398 652 90011).
Wave soldering is the preferred method for mounting of
through-hole mount IC packages on a printed-circuit
board.
Manual soldering
Apply the soldering iron (24 V or less) to the lead(s) of the
package, either below the seating plane or not more than
2 mm above it. If the temperature of the soldering iron bit
is less than 300 °C it may remain in contact for up to
10 seconds. If the bit temperature is between
300 and 400 °C, contact may be up to 5 seconds.
Soldering by dipping or by solder wave
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joints for more than 5 seconds.
