A6902D(2007) Datasheet - STMicroelectronics

Description
The A6902D is a complete and simple step down switching regulator with adjustable current limit, capable to deliver up to 1A at output voltages from 1.2V to 35V. The internal robust P-channel DMOS transistor with a typical of 250mΩ assures high efficiency and a minimum dropout even at high output current level. The internal fixed switching frequency of 250kHz, and the SO-8 package pin allow to built an ultra compact DC/ DC converter with a minimum board space.
