Description: Dual Monolithic 300mA Synchronous Step-Down Regulator

Features

* High Efﬁciency Dual Step-Down Outputs: Up to 96%
* 300mA Output Current per Channel at V = 3V IN
* Automatic Low Ripple Burst Mode Operation (20mVP-P)
* Only 40µA Quiescent Current During Operation (Both Channels)
* 2.25MHz Constant-Frequency Operation www. DataSheet4U. com
* 2.5V

Applications

* Supply current during operation is only 40µA and drops to < 1µA in shutdown. Automatic Burst Mode® operation increases efﬁciency at light loads, further extending battery life. An internally set 2.25MHz switching frequency allows the use of tiny surface mount inductors and capacitors. Internal soft
