Conv DC-DC Single Step Up 1.8V to 16V 8-Pin PDIP N

The MAX752 are fixed and adjustable CMOS, step-up, DC-DC switch-mode regulators. The MAX752 is an adjustable version that converts a minimum of +1.8V to any higher voltage up to +15V, at up to 200mA. Typical full-load efficiencies are 85% to 95%. A single 50µH inductor is suitable for the entire range of operating conditions, so no inductor related design is necessary. The MAX752 use current-mode pulse width modulation (PWM) controllers to provide precise output regulation and low sub harmonic noise. Typical no-load supply current is 2mA. A fixed 170kHz oscillator frequency allows easy filtering of ripple and noise, and provides for small external components. The MAX752 feature cycle-by-cycle current limiting, over current limiting, external shutdown, and programmable soft-start protection.
