DC-DC Controller
Description
The FP6791C is a CMOS step-up switching controller which 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 short-circuit protection delay time with an external capacitor which is connected to the CSP pin. If the maximum duty condition continues due to...
