Conv DC-DC Single Step Up 4V to 9.3V 8-Pin CDIP

The MAX732 are CMOS step-up DC-DC switch-mode regulators. The MAX732 is a +12V regulator that accepts inputs from 4.0V to 9.3V and delivers up to 200mA of DC current. Typical full-load efficiencies are 85% to 92%. They require only a single inductor value of 50µH to function over their entire ranges, so no inductor-related design is necessary. Accuracy is guaranteed over temperature, line, and load variations. The MAX732 use a current-mode pulse-width modulation (PWM) controller to provide precise output regulation and low sub harmonic noise. Typical no load supply current is 1.7mA. Fixed 170kHz oscillator frequencies allow easy filtering of ripple and noise and provide for small external components. The MAX732 feature cycle-by-cycle current limiting, over current limiting, undervoltage lockout, and programmable soft-start protection.
