MAX629ESA+ by Analog Devices

28V, Low-Power, High-Voltage, Boost or Inverting DC-DC Converter


The MAX629 low-power DC-DC converter features an internal N-channel MOSFET switch and programmable current limiting. It is designed to supply positive or negative bias voltages up to ยฑ28V from input voltages in the 0.8V to VOUT range, and can be configured for boost, flyback, and SEPIC topologies. The MAX629's 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 MAX629's 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's ideal for battery-powered applications. The MAX629 is available in an 8-pin SO package.
