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.
