General Description
The G5110 boost converter incorporate high-performance, current-mode, and frequency selectable pulse width modulation (PWM) circuitry with a built-in N-channel MOSFET to provide a highly efficient 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 performance.
