The LM2853 synchronous buck regulator is a 550 kHz step-down switching voltage regulator capable of driving up to a 3A load with excellent line and load regulation. The LM2853 accepts an input voltage between 3 V and 5.5 V and delivers a customizable output voltage that is factory programmable from 0.8 V to 3.3 V in 100 mV increments. Internal type-three compensation enables a low component count solution and greatly simplifies external component selection. The HTSSOP-14 (PWP) package enhances the thermal performance of the LM2853.
