The MAX629ESA+T is a versatile DC-DC converter IC designed for high-voltage biasing applications. It features an internal 500mA N-channel MOSFET switch, eliminating the need for an external FET. This device can generate positive or negative output voltages up to ±28V from input voltages as low as 0.8V.
With a low supply current of 80μA and a shutdown current of 1μA, the MAX629ESA+T is ideal for battery-powered applications. Its current-limited pulse-frequency modulation (PFM) control scheme ensures high efficiency across various load conditions. The high switching frequency of up to 300kHz allows for the use of small, surface-mount magnetics, contributing to a compact design.
Configurable for boost, flyback, and SEPIC topologies, this converter is suitable for applications such as LCD bias generators, high-efficiency boost converters, and varactor tuning diode bias. It is supplied in an 8-pin SOIC package, designed for surface mounting.
The operating temperature range is -40°C to +85°C, making it suitable for demanding environments. The adjustable current limit feature provides flexibility in component selection for inductors.
