Single and dual-channel DC-DC converter ICs offer enhanced protection features

Available now from Mouser, Cypress MB39x Series single and dual-channel DC-DC converter contain enhanced protection features and support ceramic capacitors. MB39x realizes rapid response, high efficiency and low ripple voltage. Its high-frequency operation enables the miniaturization of inductor and I/O capacitors. The MB39C ICs are optimal for portable device power management systems with one built-in channel of DC-DC step-down converter for digital circuits and one built-in channel of low-noise LDO for analog circuits. The DC-DC conversion circuit adopts the PFM/PWM mode to improve efficiency under light load. The current mode architecture is also adopted to achieve high-speed load response.
