Description

General part information

LM2852 Series

The LM2852 synchronous buck regulator is a high frequency step-down switching voltage regulator capable of driving up to a 2A load with excellent line and load regulation. The LM2852 can accept an input voltage between 2.85 V and5.5 V and deliver an output voltage that is factory programmable from 0.8 V to 3.3 V in 100-mV increments. The LM2852 is available with a choice of two switching frequencies –500 kHz (LM2852Y) or 1.5 MHz (LM2852X). It also features internal, type-three compensation to deliver a low component count solution. The exposed-pad HTSSOP-14 package enhances the thermal performance of the LM2852.
