Product Summary
The FP6290TR-LF is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.2Ω 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. The applications of the FP6290TR-LF are LCD Display, Digital Camera, Handheld Device, Portable Product.
