General Description
The MAX1790/MAX8715 boost converters incorporate
high-performance (at 1.2MHz), current-mode, fixed-fre-
quency, pulse-width modulation (PWM) circuitry with a
built-in 0.21
Ω
/0.15
Ω
n-channel MOSFET to provide a high-
ly efficient regulator with fast response.
High switching frequency (640kHz or 1.2MHz selectable)
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
equivalent-series-resistance (ESR) ceramic output capaci-
tors. The device can produce an output voltage as high as
12V from an input as low as 2.6V.
Soft-start is programmed with an external capacitor, which
sets the input-current ramp rate. In shutdown mode, cur-
rent consumption is reduced to 0.1μA. The MAX1790/
MAX8715 are available in a space-saving 8-pin μMAX
package. The ultra-small package and high switching fre-
quency allow the total solution to be less than 1.1mm high.
