Switching at a fixed 300 kHz, the controller lets the designer size the output inductor and filter capacitors to balance ripple against board area. The 86 % maximum duty cycle supports moderate step-down ratios at low input voltages. ## Package and temperature grade for industrial environments Housed in a 10-lead TFSOP/MSOP (3.00 mm width) with a 0.50 mm pitch, the 10-uMAX/uSOP footprint suits space-constrained power stages on multi-layer boards. Surface-mount assembly with Tape & Reel or Cut Tape packaging — the reel quantity supports production runs; Cut Tape works for prototypes or low-volume builds. Analog Devices lists the MAX8546EUB+T as Active and ROHS3 compliant. The single output, positive configuration with an Enable pin gives the system designer a clean on/off control without external sequencing logic.","metaTitle":"MAX8546EUB+T Buck Controller, 300kHz, 10-uMAX/uSOP","metaDescription":"MAX8546EUB+T step-down buck controller from Analog Devices, 2.7V-28V input, 300kHz, synchronous rectifier, -40 to 85°C, 10-uMAX/uSOP.
