1.4MHz SOT23 Current-Mode
Step-Up DC-DC Converter
General Description
The MAX1896 step-up DC-DC converter incorporates
high-performance current-mode, fixed-frequency,
pulse-width modulation (PWM) circuitry and an internal
0.7 ? N-channel MOSFET to provide a highly efficient
regulator with fast response.
High switching frequency (1.4MHz) allows fast loop
response and easy filtering with small components. The
MAX1896 can produce an output voltage as high as
13V from an input as low as 2.6V. Soft-start is program-
mable with an external capacitor, which sets the input
current ramp rate. In shutdown mode, current con-
sumption is reduced to 0.01μA.
The MAX1896 is available in a space-saving 6-pin
SOT23 package. The ultra-small package and high
switching frequency allow cost and space-efficient
implementations.
