10. Reference
10-1 Flyback Method
MB39C601 is a flyback type switching regulator controller, which is dedicated to supply to its
target LED constant. The LED current is regulated by controlling the switching on-time or
controlling the switching frequency. The LED current is converted into detecting voltage (Vs)
by sense resistance (R6) connected in series with LED. Vs is compared with the reference
voltage that sets the LED current to constant value by an external error amplifier (Err AMP).
When Vs falls below a reference voltage, Err AMP output rises and the current that flows into
the Opto-Coupler is decreased.
The configuration of MB39C601-EVB-03 is on-time control.
MB39C601 becomes to on-time control by connecting the collector of the Opto-Coupler from
OTM pin through resistance. In on-time control, it controls on-time at OTM pin current. So, ontime increases when the current of OTM pin decreases. And the average current supplied to
LED is regulated, because on-time is regulated at the constant switching frequency.
By the way, MB39C601 becomes to switching frequency control by connecting the emitter of
the Opto-Coupler from FB pin through resistance. In switching frequency control, it controls
switching frequency at FB pin current. So, switching frequency becomes high when the
current of FB pin decreases. And the average current supplied to LED is regulated, because
switching frequency is regulated at the constant on-time.

10-2 Cascode Switching
The switch in Primary Winding is a cascode connection.The gate of external MOSFET is
connected with VCG pin, and the source is connected with the drain of internal Driver
MOSFET. When the swich is on-state, internal Driver MOSFET is turned on, internal HS
Driver MOSFET is turned off, and the source voltage of external MOSFET becomes to GND.
For this period the DC bias is supplied to the gate of external MOSFET from VCG pin.
Therefore external MOSFET is turned on.
When the switch is off-state, internal Driver MOSFET is turned off, HS Driver MOSFET is
turned on, and the source voltage of external MOSFET becomes to VCG voltage. For this
period the DC bias is supplied to the gate of external MOSFET from VCG pin. Therefore
external MOSFET is turned off. Moreover, the current flowing into internal Driver MOSFET is
equal to the current of Primary Winding. Therefore, the peak current into Primary Winding can
be detected without the sense resistance.

10-3 Natural PFC (Power Factor Control) Function
In the AC voltage input, when the input current waveform is brought close to the sine-wave,
and the phase difference is brought close to Zero, Power Factor is improved. In the flyback
method operating in discontinuous conduction mode, when the input capacitance is set small,
the input current almost becomes equal with peak current of Primary Winding.

In on-time control, if loop response of ErrAMP is set to lower than the AC frequency (1/10 of
the AC frequency), on-time becomes to constant. Therefore, input current is proportional to
input voltage, so Power Factor is regulated.

10-4 Dimmer Phase Angle Detection
MB39C601 is compatible with both leading-edge and trailing-edge phase-cut dimmers. (1)
part operates as a comparator, and (2) part operates as a switched capacitor. When the
secondary side of the transformer is a positive voltage, the base of Q5 becomes 5V, Q5 is
turned on, and C12 is discharged through R27. Moreover, when the secondary side of the
transformer is a negative voltage, Q5 is turned off and C12 is charged through R27. The
average input voltage increases and decreases depending on the dimmer angle. Therefore
the voltage depending on the phase angle is maintained by C12. The voltage maintained by
C12 is amplified by OP_AMP(IC2), and the output voltage of OP_AMP is supplied as
VCOMMAND. VCOMMAND falls when the phase angle is high, VCOMMAND rises when the
phase angle is low.

The reference voltage of Err_AMP is generated by dividing VCOMMAND with R35 and R44.
Thus, the LED current is regulated depending on the phase angle.
10-5 TRIAC Holding Current
At the TRIAC dimmer, the holding current is necessary to maintain on-state of TRIAC. When
the holding current is not maintained, TRIAC is turned off. Because power consumption of the
LED lighting is lower than the light bulbs, it becomes impossible to maintain the holding
current of TRIAC at a light load. When the TRIAC phase angle is high and the LED current
decreases, the load becomes light. In this case, the flicker might be generated because the
TRIAC dimmer is irregularly turned off. Then, to maintain the holding current of TRIAC, the
load current is added. This load current circuit is added to the secondary side as shown in the
following. When VCOMMAND decreases more than the voltage set with R17 and R9, Q1 is
turned on and the load current is added through R7.
