LM2717-ADJ - Dual Step-Down DC/DC Converter

General Description

The LM2717-ADJ is composed of two PWM DC/DC buck (step-down) converters.

Both converters are used to generate an adjustable output voltage as low as 1.267V.

Both also feature low RDSON (0.16Ω) internal switches for maximum efficiency.
