GMT 致新 G5108P8U MSOP-8 电源管理芯片 科瑞芯出品

　　General Description

　　The G5108 boost converter in corporate high-performance,

　　current-mode, frequency selectable pulse

　　width modulation (PWM) circuitry with a built-in 0.2Ω

　　n-channel MOSFET to provide a highly efficient regulator.

　　High switching frequency allows easy filtering and

　　faster loop performance. An external compensation

　　pin provides the user flexibility in determining loop dynamics,

　　allowing the use of small, low ESR ceramic

　　output capacitors. The device can produce an output

　　voltage as high as 20V. User programmed soft-start

　　with an external capacitor determines the input current

　　ramp rate.

　　The G5108 is available in a space-saving MSOP-8

　　and TDFN3X3-8 package.
