Preliminary Datasheet
LP3211
High Performance PWM DC/DC Regulated
General Description
The LP3211 is a 1.2MHz high performance PWM
DC/DC converter that produces a regulated 5V output.
No external inductor and diode is required for
operation. The operating voltage range is 2.8V to Vout.
Internal soft-start circuitry effectively reduces the
in-rush current both while start-up and mode change.
The LP3211 features very low quiescent current, over
current protection and short circuit protection.
The LP3211 is available in SOT-23-6 package.
