Description
The FSDL0165RN consists of an integrated Pulse Width
Modulator (PWM) and Sense FET, and is specifically
designed for high performance off-line Switch Mode Power
Supplies (SMPS) with minimal external components. This
device is an integrated high voltage power switching regula-
tor which combines an avalanche rugged Sense FET with a
current mode PWM control block. The integrated PWM con-
troller features include: a fixed oscillator with frequency
modulation for reduced EMI, Under Voltage Lock Out
(UVLO) protection, Leading Edge Blanking (LEB), an opti-
mized gate turn-on/turn-off driver, Thermal Shut Down
(TSD) protection, Abnormal Over Current Protection
(AOCP) and temperature compensated precision current
sources for loop compensation and fault protection circuitry.
When compared to a discrete MOSFET and controller or
RCC switching converter solution, the FSDL0165RN device
reduces total component count, design size, weight while
increasing efficiency, productivity and system reliability.
This device provides a basic platform that is well suited for
the design of cost-effective flyback converters.

5. Soft Start : The FPS has an internal soft start circuit that
slowly increases the feedback voltage together with the
Sense FET current after it starts up. The typical soft start
time is 15msec, as shown in Figure 8, where progressive
increments of the Sense FET current are allowed during the
start-up phase. The pulse width to the power switching
device is progressively increased to establish the correct
working conditions for transformers, inductors, and capaci-
tors. The voltage on the output capacitors is progressively
increased with the intention of smoothly establishing the
required output voltage. It also helps to prevent transformer
saturation and reduce the stress on the secondary diode.

6. Burst Operation : In order to minimize power dissipation
in standby mode, the FPS enters burst mode operation. As
the load decreases, the feedback voltage decreases. As
shown in Figure 9, the device automatically enters burst
mode when the feedback voltage drops below
VBURH(600mV). Switching still continues but the current
limit is set to a fixed limit internally to minimize flux density
in the transformer. The fixed current limit is larger than that
defined by VFB = VBURH and therefore, VFB is driven
down further. Switching continues until the feedback voltage
drops below VBURL(350mV). At this point switching stops
and the output voltages start to drop at a rate dependent on
the standby current load. This causes the feedback voltage to
rise. Once it passes VBURH(600mV), switching resumes.
The feedback voltage then falls and the process repeats.
Burst mode operation alternately enables and disables
switching of the power Sense FET thereby reducing switch-
ing loss in Standby mode.
7. Frequency Modulation : Modulating the switching fre-
quency of a switched power supply can reduce EMI. Fre-
quency modulation can reduce EMI by spreading the energy
over a wider frequency range than the bandwidth measured
by the EMI test equipment. The amount of EMI reduction is
directly related to the depth of the reference frequency. As
can be seen in Figure 10, the frequency changes from
48.5KHz to 51.5KHz in 4ms for the FSDL0165RN. Fre-
quency modulation allows the use of a cost effective induc-
tor instead of an AC input mode choke to satisfy the
requirements of world wide EMI limits.
