The MAX629ESA is a versatile low-power DC-DC converter designed by Analog Devices for efficient power management in battery-powered applications. It can generate positive or negative bias voltages up to ±28V from input voltages as low as 0.8V.
This converter features an internal 0.5A N-channel MOSFET switch, reducing the need for external components. Its current-limited pulse-frequency-modulation (PFM) control scheme ensures high efficiency across various load conditions. With a high switching frequency of up to 300kHz, it allows for the use of small surface-mount magnetics, contributing to a compact design.
The MAX629ESA supports multiple topologies, including boost, flyback, and SEPIC configurations, making it adaptable to different circuit requirements. It is available in an 8-pin SOIC package, suitable for surface mounting.
Key electrical specifications include an input voltage range of 2.7V to 5.5V, a supply current of 80μA, and a maximum shutdown current of 1μA. The adjustable current limit feature allows for the use of small, inexpensive inductors. Its operating temperature range is -40°C to +85°C.
