Preliminary Datasheet
LP6252
High Efficiency 2.7A Synchronous Boost Convertor
General Description
The LP6252 is a Synchronous current mode boost
DC-DC converter. Its PWM circuitry with built-in 2.7A
Current power MOSFET makes this converter highly
power efficiently. Selectable high switching frequency
allows faster loop response and easy filtering with a
low noise output. The non-inverting input its error
amplifier is connected to an internal 800mV precision
reference voltage. Current mode control and external
compensation network make it easy and flexible to
stabilize the system.
