The MAX629ESA+ is a low-power, high-voltage 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 ±28V 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 magnetic.
● Generates positive or negative output voltages
● 80µA Supply current
● 1µA Maximum shutdown current
● Adjustable current limit allows use of small and inexpensive inductors
