2A Step-Up Current Mode PWM Converter

2A Step-Up Current Mode PWM Converter
FP6293
2A Step-Up Current Mode PWM Converter
General Description
The FP6293 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.1Ω
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 1.24V precision reference voltage. Current mode control and
external compensation network make it easy and flexible to stabilize the system.
The FP6293 is available in the MSOP-8L (EP) package. Combined with low ESR capacitors, it
reduced PCB space for step-up applications.
