PWM Boost DC-DC Controller
FP6791TSPTR Description
The FP6791 is a CMOS step-up switching controller
incorporates a reference voltage circuit, an oscillator,
an error amplifier, a PWM controller, an under
voltage lockout circuit (UVLO) and a timer latch
short-circuit protection circuit.
The switching frequency can be controlled by the
resistor connected to the ROSC pin and the
maximum duty ratio can be controlled by the resistor
connected to the RDuty pin.
In addition, the FP6791 provides adjustable short-
?
circuit protection delay time with an external
capacitor connected to the CSP pin. If the maximum
duty condition continues because of short-circuiting,
the capacitor externally connected to the CSP pin is
charged, and oscillation st
ops after a specific time.
This condition is cleared by re-application of power.
This controller IC allows various settings and em
?
ploys a small package, making it very easy to use.
