FP6290H

Low-Noise Step-Up Current Mode PWM Converter

General Description

The FP6290H is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.15Ω

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 package. Combined with low ESR

capacitors, it reduced PCB space for step-up applications.
