It drives an external transistor from a single output, with a 90% maximum duty cycle that suits moderate step-up ratios in portable or distributed-power rails. ## Control features and thermal range Enable and soft-start are integrated on-chip, so the designer gets sequenced turn-on without external RC networks. No synchronous rectifier means the external diode selection stays simple — a Schottky with appropriate voltage rating handles the catch function. ## Package and mounting Housed in a SOT-23-6 package (supplier device package same), surface-mount only. The six-pin footprint keeps the board area small — useful when the controller shares a tight layout with the power stage.","metaTitle":"MAX1523EUT Boost/Flyback/SEPIC Controller, SOT-23-6","metaDescription":"MAX1523EUT simple boost controller from Maxim Integrated.
