AN8011S
2-channel step-down, step-up, or inverting use
DC-DC converter control IC
s Overview
The AN8011S is a DC-DC converter control IC
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.
s Features
• PWM control frequency of 500 kHz is available.
• Wide operating supply voltage range
(VCC = 3.6 V to 34 V)
• Built-in 2-channel of open collector type for out-
put (A single-channel is also usable for inverted
amplification type)
• 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
