General Description
The G5110 boost converter incorporate high-per-formance, current-mode, and frequency selectable pulse width modulation (PWM) circuitry with a built-in N-channel MOSFET to provide a highly effi-cient regulator.
The G5110’s frequency can be selected by user to operate at either 600kHz or 1.2MHz. High switching frequency allows easily filtering and faster loop per-formance. An external compensation pin provides the user flexibility in determining loop dynamics, allowing the use of small, low ESR ceramic output capacitors. The current-mode architecture provides fast transient response to pulsed loads.
The internal N-channel MOSFET can produce output voltage as high as 22V. User programmed soft-start with an external capacitor determines the input current ramp rate.
