BA9755S
Pin No.
Pin name
1
GND
Ground
This is the common ground for the small signal system and the power system, and so requires
a stable ground suitable for common impedance.
2
PWMOUT
PWM wave output
Output is fixed at the low level when the protector circuit or thermal shutdown circuit is activated.
3
PV
CC
Power supply for the power system. Place a decoupling capacitor in proximity to this pin.
4
HDIN
HD pulse input. The input signal should be shorter than the rise time (
μ
s).
5
MMCR
Shifts the phase of the serrated wave. Use a charge resistance higher than 4.7k
.
Serrated wave output. Adjust maximum capacity by changing maximum oscillation frequency.

→
C = 2000p
AGC time constant setting.
7
AGC
Set capacity according to the linearity of the minimum oscillation frequency and the response
time during frequency change.
8
ERRIN
Input of the error amplifiers feedback voltage.
9
ERRREF
Input of the error amplifiers feedback voltage.
When this voltage is given a time constant, the IC soft-starts when the power is turned on.
10
ERROUT
Output of the error detection voltage.
Setting the time constant for the protector output suppression time and input of the beam
protectors reference voltage. This stops the protectors until the system stabilizes. The latch
can be unlocked by raising the voltage of this pin above 4.5V.
11
PON DET
12
ABLIN
Beam protector input. When the protector is activated, the latch locks and PWM output is fixed
at the low level.
13
XRAYIN
X-ray protector input. When the protector is activated, the latch locks and PWM output is fixed
at the low level.
14
XREF
Input of the X-ray protector's reference voltage.
15
VREG6
Reference voltage output (6V). Output variation is guaranteed to be 1% or less (with trimming).
This circuit is completely separate from the 9V system. Output is stopped when the thermal
shutdown circuit is activated. Use a 47
μ
F bypass capacitor.
16
VREG9
Reference voltage output (9V). Output variation is guaranteed to be 1% or less (with trimming).
This circuit is completely separate from the 6V system. Output is stopped when the thermal
shutdown circuit is activated. Use a 10
μ
F bypass capacitor.
17
PROTOUT
Protector output.
Output changes to the high level when the protector circuit or thermal shutdown circuit is activated.
18
Power supply for the signal system.
Place a decoupling capacitor in proximity to this pin.
