with two-channel output using the PWM method
which allows 500 kHz high-speed control.
Respecitve output operation can be completely
synchronized with each other by using the same
oscillation output.

• Each output can be stopped independently by the
external control .
• Built-in on/off function for the operation/stop of IC Incorporating circuit for short-circuit portection and under-
voltage lock-out (U.V.L.O.)
• The latch circuit is externally controllable.
• Low consumption current (during operation: 5 mA, during standby: 2 µA)
s Applications
• LCD displays, digital still cameras, and PDAs
