MAX17067
Low-Noise Step-Up DC-DC Converter
Compact, High-Efficiency Boost Converter
|
Status
Active: In Production.
Description
The MAX17067 boost converter incorporates high-performance (at 1.2MHz), current-mode, fixed-frequency, pulse-width modulation (PWM) circuitry with a built-in 0.15Ω 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 available 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.
