Low-Noise Step-Up DC-DC Converter
General Description
The MAX17067 boost converter incorporates high-
performance (at 1.2MHz), current-mode, fixed-frequency,
pulse-width modulation (PWM) circuitry with a built-in
0.15 Ω n-channel MOSFET to provide a highly efficient
regulator with fast response.
High switching frequency (640kHz or 1.2MHz selectable)
allows for easy filtering and faster loop performance. An
external compensation pin provides the user flexibility in
determining loop dynamics, allowing the use of small,
low equivalent-series-resistance (ESR) ceramic output
capacitors. The device can produce an output voltage
as high as 18V.
Soft-start is programmed with an external capacitor, which
sets the input-current ramp rate. The MAX17067 is avail-
able in a space-saving 8-pin μMAX ? package. The ultra-
small package and high switching frequency allow the
total solution to be less than 1.1mm high.
