Product Summary
The MAX629ESA+T is a low-power DC-DC converter. The MAX629ESA+T features an internal N-channel MOSFET switch and programmable current limiting. It is designed to supply positive or negative bias voltages up to ±28V from input voltages in the 0.8V to VOUT range, and can be configured for boost, flyback, and SEPIC topologies. The MAX629ESA+T current-limited pulse-frequency-modulation (PFM) control scheme provides high efficiency over a wide range of load conditions. An internal, 0.5A N-channel MOSFET switch reduces the total part count, and a high switching frequency (up to 300kHz) allows for tiny surface-mount magnetics. The MAX629ESA+T combination of low supply current, logic-controlled shutdown, small package, and tiny external components makes it an extremely compact and efficient high-voltage biasing solution that is ideal for battery-powered applications. The MAX629ESA+T is available in an 8-pin SO package.
