It integrates a synchronous rectifier, so no external Schottky diode is needed, and the switching frequency is programmable from 100kHz to 2.2MHz, letting you trade efficiency against inductor size. The device operates over a -40°C to 125°C junction temperature range, making it suitable for under-hood automotive, industrial 24V rails, and outdoor telecom equipment where the supply can swing from cold-crank to load-dump transients. ## 1.7A output with synchronous rectification The 1.7A continuous output covers point-of-load rails for sensors, small motors, or auxiliary logic supplies. The synchronous rectifier eliminates the need for an external Schottky diode. ## Active lifecycle and sourcing posture The MAX17545ATP+T carries an Active product status with ROHS3 compliance. ## Package and footprint Housed in a 20-TQFN (4x4 mm) with exposed pad, the part is surface-mount and requires a thermal via array under the pad to carry dissipation.","metaTitle":"MAX17545ATP+T Buck Regulator, 4.5V-42V Input, 1.7A Output","metaDescription":"MAX17545ATP+T Himalaya step-down regulator: 4.5V to 42V input, 1.7A adjustable output, 100kHz-2.2MHz switching, -40°C to 125°C.
