SAFETY PRECAUTIONS
The following items should be checked for continued protection of the customer and the service technician.

Before Servicing
Leakage current check

This Unit
Before returning the set to the customer, be sure to carry out either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chas-
sis to either side of the power cord is less than 460 kohms, the set is defective.
Be sure to test for leakage current with the AC plug in both polarities, in addition, when the set's power is in each state (on, off and standby mode), if applicable.

Please heed the following cautions and instructions during servic-

ing and inspection.
◎ Heed the cautions! Many of the electric and the structural parts used in the set have special safety properties. In most cases

wearing gloves when servicing while the set is energized, or by unplugging the power cord when
replacing parts, for example. (1) Schematic diagrams Indicated by the z mark.
(2) There are high voltage parts inside. Handle with extra care when the set is energized. (2) Parts lists Indicated by the z mark.

Through great care is taken when parts were manufactured from sheet metal, there may be burrs on the
edges of parts. The burrs could cause injury if fingers are moved across them in some rare cases. Wear

gloves to protect your hands.
◎ Use only designated parts!
The set's parts have specific safety properties (fire resistance, voltage resistance, etc.). Be sure to use
parts which have the same properties for replacement. The burrs have the same properties. In particular,
for the important safety parts that are indicated by the z mark on schematic diagrams and parts lists,
be sure to use the designated parts.
◎ Be sure to mount parts and arrange the wires as they were originally placed!
For safety seasons, some parts use tapes, tubes or other insulating materials, and some parts are mount-
ed away from the surface of printed circuit boards. Care should also be taken with the positions of the

Repair Information
wires by arranging them and using clamps to keep them away from heating and high voltage parts, so
be sure to set everything back as it was originally placed.
◎ Make a safety check after servicing!
Check that all screws, parts and wires removed or disconnected when servicing have been put back
in their original positions, check that no serviced parts have deteriorated the area around. Then make
an insulation check on the external metal connectors and between the blades of the power plug. And
otherwise check that safety is ensured.
(Insulation check procedure)
Unplug the power cord from the power outlet, disconnect the antenna, plugs, etc., and on the power.
Using a 500V insulation resistance tester, check that the insulation resistance value between the inplug
and the externally exposed metal parts (antenna terminal, headphones terminal, input terminal, etc.) is
1M Ω or greater. If it is less, the set must be inspected and repaired.

1. C13, PC14 and PC15 are supplied through the power switch. Since the switch only sinks a limited
amount of current (3 mA), the use of GPIOs PC13 to PC15 in output mode is limited:
- The speed should not exceed 2 MHz with a maximum load of 30 pF.
- These GPIOs must not be used as current sources (e.g. to drive an LED).
2. This feature is available on STM32F030x6 and STM32F030x4 devices only.
3. This feature is available on STM32F030x8 devices only.
4. For STM32F030x4/6/8 devices only.
5. For STM32F030xC devices only.
6. On LQFP32 package, PB2 and PB8 should be treated as unconnected pins (even when they are not

available on the package, they are not forced to a defined level by hardware).
7. After reset, these pins are configured as SWDIO and SWCLK alternate functions, and the internal pull-
up on SWDIO pin and internal pull-down on SWCLK pin are activated.

quasi-resonant operation is selected, the oscillator (pin 13, OSC) determines the
maximum allowed operating frequency.

Electrical
Fixed-frequency operation is selected if the pin is not tied to VREF, in which case
12 MODE/SC the oscillator determines the actual operating frequency, the maximum allowed
duty cycle is set at 70 % min. and the pin delivers a voltage ramp synchronized to
the oscillator when the gate-drive output is high; the voltage delivered is zero while
the gate-drive output is low. The pin is to be connected to pin CS (7) via a resistor
for slope compensation.
Oscillator pin. The pin is an accurate 1 V voltage source, and a resistor connected
from the pin to GND (pin 3) defines a current. This current is internally used to set
13 OSC the oscillator frequency that defines the maximum allowed switching frequency of
the L6566B, if working in QR mode, or the operating switching frequency if working
in FF mode.
Soft-start current source. At start-up a capacitor Css between this pin and GND
(pin 3) is charged with an internal current generator. During the ramp, the internal
reference clamp on the current sense pin (7, CS) rises linearly starting from zero to

Mechanical
its final value, thus causing the duty cycle to increase progressively starting from
14 SS zero as well. During soft-start the adaptive UVLO function and all functions
monitoring pin COMP are disabled. The soft-start capacitor is discharged whenever
the supply voltage of the IC falls below the UVLO threshold. The same capacitor is
used to delay IC’s shutdown (latch-off or auto-restart mode selectable) after
detecting an overload condition (OLP).
Line voltage feedforward input. The information on the converter’s input voltage is
fed into the pin through a resistor divider and is used to change the setpoint of the
pulse-by-pulse current limitation (the higher the voltage, the lower the setpoint).
The linear dynamics of the pin ranges from 0 to 3 V. A voltage higher than 3 V
15 VFF
makes the IC stop switching. If feedforward is not desired, tie the pin to GND (pin 3)
directly if a latch-mode OVP is not required (see pin 11, ZCD) or through a 10 kΩ

min. resistor if a latch-mode OVP is required. Bypass the pin with a capacitor to
GND (pin 3) to reduce noise pick-up.
Brownout protection input. A voltage below 0.45 V shuts down (not latched) the IC,
lowers its consumption and clears the latch set by latched protections (DIS > 4.5 V,
SS > 6.4 V, VFF > 6.4 V). IC’s operation is re-enabled as the voltage exceeds
0.45 V. The comparator is provided with current hysteresis: an internal 15 µA
16 AC_OK
current generator is ON as long as the voltage on the pin is below 0.45 V and is
OFF if this value is exceeded. Bypass the pin with a capacitor to GND (pin 3) to
reduce noise pick-up. Tie to Vcc with a 220 to 680 kΩ resistor if the function is not
used.
