LM2852 2A 500/1500kHz Synchronous SIMPLE SWITCHER ® Buck Regulator October 2006 www.DataSheet4U.com LM2852 2A 500/1500kHz Synchronous SIMPLE SWITCHER ® Buck Regulator General Description The LM2852 SIMPLE 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 2.85V and 5.5V and deliver an output voltage that is factory programmable from 0.8V to 3.3V in 100mV increments. The LM2852 is available with a choice of two switching frequencies - 500kHz (LM2852Y) or 1.5MHz (LM2852X). It also features internal, type-three compensation to deliver a low component count solution. The exposed-pad TSSOP-14 package enhances the thermal performance of the LM2852.
