High Efficiency 7A Synchronous Boost Convertor
General Description
The LP6253 is a synchronous current mode boost
DC-DC converter. Its PWM circuitry with built-in
7A(ESOP8) 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
0.5V(TQFN-16)/0.8V(ESOP8)
precision
reference
voltage.
Current
mode
control
and
internal
compensation network make it easy and flexible to
stabilize the system.
