Circuit Description

Oscillator (osc)

The oscillator is generating a frequency

twice the switching frequency

_switch= 100 kHz. Resistor, capacitor and

current source which determine the

frequency are integrated. The charging

The TDA 16831-4 is a current mode pulse

width modulator with integrated sense

CoolMOS transistor. It fulfills the

requirements of minimum external control

circuitry for a flyback application.

f

and

discharging

current

of

the

Current mode control means that the

current through the MOS transistor is

compared with a reference signal derived

from the output voltage of the flyback

application. The result of that comparison

determines the on time of the MOS

transistor.

implemented oscillator capacitor is

internally trimmed, in order to achieve a

very accurate switching frequency.

Temperature coefficient of switching

frequency is very low ( see page 19).

Divider Flip Flop (tff)

To minimize external circuitry the sense

resistor which gives information about

MOS current is integrated. The oscillator

resistor and capacitor which determine the

switching frequency are integrated, too.

Tff is a flip flop which divides the oscillator

frequency by one half to create the

switching frequency. The maximum duty

cycle is set to Dmax = 0.5.

Special efforts have

compensate temperature dependency and

to minimize tolerances of this resistor.

been made to

Current Sense Amplifier (pwmop)

The positive input of the pwmop is applied

to the internal sense resistor. With the

internal sense resistor (R_sense) the sensed

current coming from the CoolMOS is

converted into a sense voltage. The sense

voltage is amplified with a gain of 32 dB.

The amplified sense voltage is connected

to the negative input of the pwm

comparator. Each time when the CoolMOS

transistor is switched on, a current spike is

superposed to the true current information.

To eliminate this current spike the sense

voltage is smoothed via an internal resistor

capacitor network with a time constant of

T_d1= 100 ns. This is the first leading edge

blanking and only a small spike is left. To

reduce this small spike the current sense

amplifier is creating a virtual ramp at the

output. This is done by a second resistor

capacitor network with T_d2= 100 ns and an

op-offset of 0.8 V which is seen at the

output of the amplifier. When gate drive is

The circuit in detail: (see Figure 3)

Start Up Circuit (uvlo)

Uvlo is monitoring the external supply

voltage V_CC. When V_CCis exceeding the on

threshold V_CCH= 12 V, the bandgap, the

bias circuit and the soft start circuit are

switched on. When V_CCis falling below the

off-threshold V_CCL= 9 V the circuit is

switched off. During start up the current

consumption is about 30 µA.

Bandgap (bg)

The bandgap generates an internal very

accurate reference voltage of 5.5 V to

supply the internal circuits.

Current Source (bias)

The bias circuit provides the internal

circuits with constant current.

switched off the output capacitor is Logic (logpwm)

discharged via pulse signal pwmpls. The

The logic logpwm comprises a RS-flip-flop

and a NAND-gate. The NAND-gate

insures that CoolMOS transistor is only

switched on when sosta is on and pwmin

has exceeded minimum threshold and

oscillator signal slogpwm sets the RS-flip-

flop. The gate drive circuit is switched on,

when capacitor voltage exceeds the

internal threshold of 0.4 V. This leads to a

linear ramp, which is created by the output

of the amplifier. Therefore duty cycle of

0 % is possible. The amplifier is

compensated through an internal compen-

sation network.

pwmin

pwmrmp

currentshutdown is off and tempshutdown

is off and tff sets the starting impulse.

CoolMOS transistor is switched off when

pwmrmp exceeds pwmin or duty cycle

exceeds 0.5 or pwmcs exceeds I_maxor

silicium temperature exceeds T_maxor uvlo

is going below threshold. The RS flip flop

ensures that with every frequency period

only one switch on can occur (double pulse

suppression).

The transfer function of the amplifier can

be described as

V_o

----- = -----------------------------------; p = jω

V_ip × (1 + T × p)

K_i

Gate Drive (gtdrv)

Gtdrv is the driver circuit for the CoolMOS

and is optimized to minimize EMI

influences and to provide high circuit

efficiency. This is done by smoothing the

switch on slope when reaching the

CoolMOS threshold. Leading switch on

spike is minimized then. When CoolMOS

is witched off, the falling slope of the gate

driver is slowed down when reaching 2 V.

So an overshoot below ground can't occur.

Also gate drive circuit is designed to

eliminate cross conduction of the output

stage.

Comparator (pwmcomp)

The comparator pwmcomp compares the

amplified current signal pwmrmp of the

CoolMOS with the reference signal pwmin.

Pwmin is created by an external

optocoupler or external transistor and

gives the information of the feedback

circuitry. When the pwmrmp exceeds the

reference signal pwmin the comparator

switches the CoolMOS off.

Current Shut Down (cssd)

Current shut down circuit switches the

CoolMOS immediately off when the sense

current is exceeding an internal threshold

of 100 mV at R_sense
