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.
Features:
；Adjustable Output from VCC to 12V
；Internal Fixed PWM Frequency: 640KHz / 1.2MHz
；Frequency Selection Pin
；Precision Feedback Reference Voltage: 1.24V
；Internal 0.15, 3A, 14V Power MOSFET
；External Programmable Soft-Start Function (SS)
；Shutdown Current : 0.1μA
；Over Current Protection
；Package: SOP-8L (EP), DFN-8L(EP)
