致新GMT G5108P8U低噪声升压DC-DC变换器

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.
