95% Efficient at 2MHz 42V Sync Buck

Linear Technology’s family of high voltage synchronous step-down DC/DC switching regulators offer up to 95% efficiency. Switching at 2MHz, these low EMI parts utilize the Silent Switcher technology. Other features include spread spectrum frequency modulation, ultra-low quiescent current and are available with single, dual, triple and quad outputs.
