It accepts a supply voltage from 3 V to 16.5 V, making it suitable for battery-powered or multi-rail systems where the input varies. ## Single-output transistor driver with enable control The controller drives an external N-channel MOSFET via a single transistor-driver output, configured for positive output voltage. An enable pin allows the regulator to be shut down without removing the input supply. No synchronous rectifier is built in, so the external diode and FET selection govern the efficiency at high step-up ratios. ## 8-SOIC surface-mount package, tube delivery The surface-mount footprint mates with standard SOIC-8 land patterns and is compatible with reflow soldering profiles typical of mixed-signal boards.","metaTitle":"Analog Devices MAX1771CSA+ Boost/Buck-Boost Controller","metaDescription":"MAX1771CSA+ step-up/step-down controller, 300kHz switching, 92% duty cycle, 3-16.5V supply.
