Function Description
Startup control
frequency internally decreases to lower the switching
power loss and improve the conversion efficiency. If FB is
less than 2.4V(Typ), the cycle of the oscillator will increase
with it, the less FB is, the wider the ccle of the oscillator
is, until the oscillation stop.
Startup current of SDC606P is designed to be very low so
that VCC could be charged up above UVLO threshold level
and device starts up quickly. A large startup resistor can
therefore be used to minimize the power loss yet achieve
a reliable startup in application.
Power transistor drive
During the ON cycle, OB pin upplies base current for the
power transistor, lls down the emitter of the power
transistor to IS, and is adaptive to the IS current. If the
current of IS ds the specified current of FB, SDC606P
will turn into the OFF cycle. During the OFF cycle, OB is
pulled down, the power transistor will shut off.
PWM control
The peak current (sensed on the IS pin) is set by the
voltage on FB pin. By comparing the voltage on FB pin and
the IS ramp voltage, the duty-cycle of the PWM
modulator is thus adjusted to provide the necessary load
current at the desired output voltage. FB can be
controlled by internal control circuit and external
feedback circuit.
Over temperature protection
When IC’s internal temperature reaches 150°C, FB voltage
will be pulled down by internal control circuit, the
switching frequency decreases or shut off. This protection
protects the IC from over temperature.
VCC over voltage protection
VCC over voltage protection circuit is integrated into IC.
When VCC voltage reaches 12V(TYP), FB ge is pulled
down via internal control circuit, then the M switching
is shut off. When VCC voltage goes down below 12V(TYP),
the switching is reactivated. The VCC over voltage
protection ensures IC to operate reliably.
Cooling requirements
Layout is important for all switching regulators. To achieve
high efficiency, good regulation, and stability, a well
designed printed circuit board layout is required. The main
power loss inside IC is produced by the internal transistor,
an extra copper plane at the pin7 and pin8 help dissipate
the heat generated by losses in transistor. For a typical
application (AC input from 85V to 265V, 12W output), and
200mm2 copper plane is necessary.
Current limit
The output is shut off to limit the power when voltage of
IS Pin exceeds Current sense threshold voltage.
Gremode control
Under no-load and light-load condition, the switching
