4.5V to 28V input, 1.4mA supply current
The MAX8664AEEP+ is a dual-output power-supply controller from Analog Devices that accepts a 4.5V to 28V input supply — wide enough to cover 5V, 12V, and 24V industrial rails without an external pre-regulator. Its own supply current is just 1.4mA, so the controller's overhead does not eat into the efficiency budget of the downstream power stage.
Industrial temperature range and package
Housed in a 20-QSOP package (3.90mm body width, 0.154" pitch), it is a surface-mount controller that fits on compact PCBs alongside the switching FETs and output inductors.
