Product Details
The MAX732 is a step-up DC-DC switchmode regulator
with an output of +12V. The input voltage can be between 4.0V to 9.3V and
the device is capable of supplying up to 200mA of output current.
The MAX732 requires only a single external inductor and has a typical
efficiency of 85% to 92%. The MAX732 operates at a fixed oscillator
frequency of 170kHz.
