It drives an external N-channel MOSFET with synchronous rectification, targeting point-of-load and intermediate bus conversion from 2.7 V to 28 V input rails. Switching at 300 kHz, the controller delivers a single positive output with a maximum duty cycle of 86%. The synchronous rectifier eliminates the freewheeling diode, improving efficiency at low output voltages typical of 3.3 V and 1.8 V rails. The enable control feature allows the regulator to be sequenced or shut down from a logic signal.","metaTitle":"MAX8546EUB+ Buck Controller, 300kHz, 10-uMAX/uSOP","metaDescription":"Analog Devices MAX8546EUB+ active step-down controller, 2.7-28V input, 300kHz, synchronous rectifier. 10-uMAX/uSOP package.
