聯(lián)系我們詳情
The FP6791C 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 FP6791C provides adjustable shortcircuit 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 stops after a specific time. This condition is cleared by re-application of power. This controller IC allows various settings and employs a small package, making it very easy to use.
