FC
Control amplifier frequency correction
Current limiter system closed loop oscillation can be prevented by
inserting a capacitor (about 0.022 to 0.47 μF) between this pin and
ground. If the capacitance of this capacitor is too large, the output
current response characteristics may be degraded.
16
EO
Error amplifier output
When high, the output current is increased.
Control
amplifier
17
EI
Error amplifier input
18
PD
Phase comparator output (PLL output)
The phase error is output as changes in the duty of a pulse waveform.
The output current is increased as the duty becomes smaller.
19
CLD
LD output mask time setting
Chattering can be masked by inserting a capacitor (about 0.1 to 0.47
μF) between this pin and ground. The startup time may be increased if
only masking is used and the servo constants are not re-optimized.
