LM5146RGYR TI DC DC Switching Controllers
The LM5146 is a 100-V synchronous buck controller for high-current step-down converters, operating from a 6-V to 100-V input. It features emulated current-mode control for fast transient response, programmable switching frequency from 100 kHz to 1 MHz, and dual high-current gate drivers (3-A sink/2-A source). Packaged in a 20-pin VQFN (RGY) (4.5 mm × 3.5 mm) with PowerPAD, it is ideal for industrial and automotive high-current converters. Applications include telecom and 48-V battery systems, solar-powered battery chargers, and electric vehicle power distribution. In stock at HL Electronics – request a quote for fast delivery.
