MAX8668ETEX+T Description

Short technical summary and product information.

The MAX8668ETEX+T by Analog Devices is a versatile dual step-down DC-DC converter integrated with dual low-dropout (LDO) linear regulators. This device is designed to power low-voltage microprocessors and DSPs in portable applications, offering high efficiency and a compact external component size.

The step-down converters provide adjustable output voltages ranging from 0.6V to 3.3V. OUT1 is guaranteed to deliver 600mA, while OUT2 supports up to 1200mA. The integrated LDOs offer a guaranteed 300mA output current and operate down to a 1.7V supply voltage, with low output noise.

Featuring a 1.5MHz hysteretic-PWM control scheme, the MAX8668ETEX+T enables the use of tiny external components. It includes individual enables for each output, maximizing design flexibility. The device operates with a low supply current of 25µA per output and a no-load operating current of 100µA with all outputs enabled.

Available in a space-saving 3mm x 3mm, 16-pin thin QFN package, this component is suitable for space-constrained designs. Applications include cell phones, smartphones, PDAs, portable media players, digital cameras, and handheld instruments.
