The FP6290H is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.15? 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. Soft-Start time can be programmed with an external capacitor, which sets the input current ramp rate. Current mode control and external compensation network make it easy and flexible to stabilize the system.
The FP6290H is available in the SOP-8L (EP) and DFN-8L (EP) package. Combined with low ESR capacitors, it reduced PCB space for step-up applications.
