FP6293
1MHz, 3.5A Step-Up Current Mode PWM Converter
General Description
The FP6293 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.14Ω
power MOSFET make this regulator highly power efficient. The internal compensation network also
minimizes as much as 6 external component counts. The non-inverting input of error amplifier connects
to a 0.6V precision reference voltage and internal soft-start function can reduce the inrush current.
The FP6293 is available in the DFN-8L/SOP-8L(EP) package and provides space-saving PCB
for the application fields.
