MAX632ACSA

MAX632ACSA Description

The MAX632ACSA is an adjustable/fixed-output switching voltage regulator from Analog Devices Inc./Maxim Integrated, designed for efficient DC-DC conversion in compact electronic systems. Operating within an input voltage range of 2V to 16.5V, it delivers a regulated output voltage adjustable down to 1.31V or fixed at 12V, with a maximum output voltage of 18V (Switch). This boost/charge pump topology regulator supports a 450mA (Switch) output current, making it suitable for low-to-medium power applications. Housed in an 8-pin SOIC package, it features a 50kHz switching frequency and operates within a 0°C to 70°C temperature range.
