CT:
The terminal used for connecting a timing
capacitor to set oscillator frequency. Use a
capacitance value within the range of 100 pF
to 0.1mF. For frequency setting method, re-
fer to the "Application Notes, [2] Function
descriptions" section. Use the oscillation fre-
quency in the range of 1 kHz to 500 kHz.
RT:
The terminal used for connecting a timing
resistor to set oscillattion frequency.
Use a resistance value ranging from 5.1 k
to 20 k .
The terminal voltage is 0.67 V typ.
On/Off:
The terminal for on/off control.
High-level input: normal operation
(V
Low-level input: standby state
The total current consumption in the standby
state can be suppressed to a value below 5 A.
IN 2:
The terminal for the inverted input of ch.2
error amplifier. Use a common-mode input
ranging from
