The LP6253H is a synchronous current mode boost DC-DC converter. Its PWM circuitry with built-in 8A current power MOSFET makes this converter highly efficient. 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 1.21V precision reference voltage. Current mode control and internal compensation network make it easy and flexible to stabilize the system.
