Product details

Boost regulator with a 750 mA switch in a 3x3 TDFN

The Maxim MAX8569AETT+T is a step-up (boost) switching regulator with an adjustable output voltage, built around a 750 mA internal switch. It accepts an input from 1.5 V up to 5.5 V, making it suitable for single-cell alkaline, NiMH, or Li-ion battery-powered designs. The output can be set from a 2 V minimum up to 5.5 V via external feedback resistors. Synchronous rectification is integrated, so no external Schottky diode is needed for the boost path — that saves a component and a bit of board area.

Without a proper via stitch under the pad, the junction temperature will climb quickly at high output.

Frequently asked questions

What is the output current capability of MAX8569AETT+T?

The internal switch is rated for 750 mA. Practical output current depends on input voltage, output voltage, and inductor selection — expect roughly 300–400 mA at 5 V out from a 3.3 V input.

What package does MAX8569AETT+T come in?

It is supplied in a 6-pin TDFN (3x3 mm) with an exposed pad, surface-mount package. Available in tape-and-reel or cut-tape formats.
