Input From Controller: Connect the included ribbon cable to this connector and to

the corresponding connector on the MAS controller. This cable passes audio signals
from the controller to the amplifier, and it transfers DC power from the amplifier
to the controller. If this cable is ever damaged, do not use it, and contact Harman
Kardon for a replacement.

AC Power Input: After you have made all other connections, plug the AC power cord

into this receptacle and into an unswitched wall outlet.

NOTE: MAS 101/111 systems require 23OV, 50/60Hz AC current. MAS 102
systems require 120V, 60HZ AC current.

FAN7602

Description

The FAN7602 is a green current mode PWM controller.
It is specially designed for off-line adapter application,
DVDP, VCR, LCD monitor application, and auxiliary
power supplies.

The internal high-voltage start-up switch and the burst
mode operation reduce the power loss in standby mode.
Because of the internal start-up switch and the burst
mode, it is possible to supply 0.5W load limiting the input
power under 1W when the input line voltage is 265Vac.
On no-load condition, the input power is under 0.3W.

The maximum power can be limited constantly, regard­less of the line voltage change using the power limit
function.

The switching frequency is internally fixed to be 65kHz
and the frequency modulation technique reduces EMI.

The FAN7602 includes various protections for the sys­tem reliability and the internal soft start prevents the out­put voltage over-shoot at start-up.

Pin Definitions

Pin Number Pin Name Pin Function Description

1LUVPLine Under Voltage Protection Pin. This pin is used to protect the set when the

input voltage is lower than the rated input voltage range.

2 Latch/Plimit Latch Protection and Power Limit Pin. When the pin voltage exceeds 4V, the latch

protection works and the latch protection is re set when the Vcc voltage is lowe r than
5V. For the power limit function, the OCP level decreases as the pin voltage
increases.

3CS/FBCurrent Sense and Fee dback Pin. This pin is used to sense the MOSFET current

for the current mode PWM and OCP. The output volta ge feedback information and
the current sense information are added using external RC filter.

4GNDGround Pin. This pin is used for the ground potential of all the pins. For proper oper-

ation, the signal ground and the power ground should be separated.

5OUTGate Drive Output Pin. This pin is an output pin to drive an external MOSFET. The

peak sourcing current is 450mA and the peak sinking current is 600mA. For prop er
operation, the stray inductance in the gate driving path must be minimized.

6VccSupply Voltage Pin. IC operating current and MOSFET driving current are supplied

using this pin.
7NCNo Connection.
8 Vstr Start-up Pin. This pin is used to supply IC operating current during IC start-up. After

start-up, the internal JFET is turned off to reduce power loss.

Description

The FSFR-series are a highly integrated power switches
designed for high-efficiency half-bridge resonant
converters. Offering everything necessary to build a
reliable and robust resonant converter, the FSFR-series
simplifies designs and improves productivity, while
improving performance. The FSFR-series combines
power MOSFETs with fast-recovery type body diodes, a
high-side gate-drive circuit, an accurate current
controlled oscillator, frequency limit circuit, soft-start, and
built-in protection functions. The high-side gate-drive
circuit has a common-mode noise cancellation
capability, which guarantees stable operation with
excellent noise immunity. The fast-recovery body diode
of the MOSFETs improves reliability against abnormal
operation conditions, while minimizing the effect of the
reverse recovery. Using the zero-voltage-switching (ZVS)
technique dramatically reduces the switching losses and
efficiency is significantly improved. The ZVS also
reduces the switching noise noticeably, which allows a
small-sized Electromagnetic Interference (EMI) filter.

The FSFR-series can be applied to various resonant
converter topologies such as series resonant, parallel
resonant, and LLC resonant converters.
