It uses a single inductor in a buck-boost topology, switching at 300 kHz to drive an external transistor. The controller is configured for a single negative output and includes an Enable control feature. The 3 V to 16.5 V supply range lets it work from common rails, making it a flexible choice for generating a negative bias rail in systems that only have positive supplies. ## Package and mounting Housed in an 8-SOIC package (0.154\" body width, 3.90 mm) with a surface-mount footprint, the MAX774CSA+ is a standard layout component that reflows alongside other SOIC-8 parts. No synchronous rectifier is built in, so the external diode and MOSFET selection determine the efficiency curve. ## Temperature grade and environment Rated for the commercial temperature range of 0°C to 70°C, this controller is intended for indoor, temperature-controlled environments such as bench power supplies, lab instruments, telecom line cards, and industrial control boards that stay above freezing. It is not specified for automotive or extended industrial use where ambient temperatures drop below 0°C or exceed 70°C. ## Lifecycle and sourcing The MAX774CSA+ carries an Active product status with ROHS3 compliance, so there is no imminent last-time-buy risk. It remains a current-production part suitable for new designs and ongoing production.","metaTitle":"MAX774CSA+ Buck-Boost Controller, 300kHz, 8-SOIC","metaDescription":"MAX774CSA+ step-up/step-down PWM controller from Analog Devices. 300kHz switching, 3V to 16.5V supply, 8-SOIC.
