微源半导体 LP6252 SOT23-6/DFN-6(2*2) 高效2.7A同步升压变换器

General Description

The LP6252 is a current mode, constant frequency step-up converter. It has typical 2.7A switch current limit. The LP6252 operates with a switching frequency at 1MHz with internal compensation, which reduces the number of external components and minimizes the size of inductor and capacitor.
The devices allows the extern resistor to program the output voltage, it can support output up to 5.5V.In shutdown mode ,the output is disconnected form the input and current consumption is reduced to less than 1 μA.
The devices are available in SOT23-6 and TDFN-6 package.
