Note: Please set the pin PWM to High when PWM control function is not used.
2. Standby Circuit
All circuits are turned off except the standby circuit and the charge pump circuit under the standby
condition.
Input voltage range is shown below. Input at CMOS and TTL level is possible. Input signal has 0.2-V
(typ.) hysteresis.

: 2 to V

INSL
: GND to 0.8 V
Please avoid controlling the output by inputting PWM signal to the standby pin. The output signal
becomes unstable and it may cause the destruction of the IC.
The charge pump circuit is turned On/Off by the switch of the input signal from the standby pin. If the
switching cycle is shorter than 50 ms, the charge pump circuit will not operate with precise timing.
Therefore, switching cycle of the standby pin should be longer than 50 ms.
When the Standby condition is changed to the Operation Mode, set IN1 and IN2 to Low level (Stop
Mode) at first. Then switch IN1 and IN2 to High level when the charge pump circuit reaches the stable
condition, VcpA is about V
