CS2001YDWFR20

Overview

The CS2001YDWFR20 is a switching and linear regulation chip manufactured by onsemi. It utilizes a dual-inline surface-mount 20-pin SO package. The device supports a maximum input voltage of 25V and provides an adjustable output voltage with a maximum limit of 7V. Output current control is achieved through two distinct modes: the switching adjustment section handles up to 1.2A, while the linear section operates at 5V with a current capacity of 100mA.

Feature Summary

• Integrates both switching and linear regulation capabilities within a single component for versatile power management.
• Features adjustable output voltage parameters to accommodate specific circuit requirements.
• Provides independent current control mechanisms for switching and linear operational sections.

Applications

• Power supply systems requiring combined switching and linear regulation stages
• Electronic devices needing adjustable voltage outputs with controlled current limits
• Circuits utilizing 25V input sources for downstream regulation
