It operates from a 14V to 100V Vcc/Vdd supply and switches at up to 2MHz, enabling compact magnetics and high power density. The controller integrates frequency control, soft start, and synchronization, along with fault protection including current limiting, over-temperature, and over-voltage. Housed in a 28-HTSSOP package with exposed pad for thermal management, it is rated for -40°C to 125°C junction temperature, suiting industrial, telecom, and automotive power stages. ## What the ratings mean for the power stage The 14V to 100V supply range covers standard 24V, 48V, and 72V industrial buses. The 2MHz switching ceiling lets you shrink the transformer and output filter — useful when board area is tight or you need fast transient response. The -40°C to 125°C TJ rating means the controller can sit next to hot magnetics or in an engine bay without derating headaches. No internal switches means you select external MOSFETs sized for your load current and voltage stress. ## Lifecycle and sourcing reality The LM5046MH/NOPB carries an Active product status with ROHS3 compliance. No end-of-life notice or last-time-buy window is recorded.","metaTitle":"LM5046MH/NOPB Full-Bridge PWM Controller, 2MHz, 28-HTSSOP","metaDescription":"Texas Instruments LM5046MH/NOPB full-bridge PWM controller. 14V-100V supply, 2MHz switching, -40°C to 125°C.
