NX2837CUPTR Description

Short technical summary and product information.

The NX2837CUPTR controller IC by Microsemi Corporation is a single power supply synchronous Buck controller optimized for step-down DC-to-DC converter applications. It efficiently converts bus voltages from 9V to 22V to a fixed 5V output. This 5V switching output serves as the input for an internal 3.3V LDO, capable of providing up to 700mA of current.

 

The device operates at a fixed 350kHz frequency and incorporates features such as internal digital soft start, adaptive deadband control, and fixed current limiting with hiccup mode. It also includes a 3.3V LDO with a power good indicator, thermal shutdown, and Vcc undervoltage lockout.

 

The NX2837CUPTR is available in a 10-MSOP-EP package suitable for surface mounting. Its Pb-free and RoHS compliant status makes it suitable for various applications including LCD TVs, graphic cards, hard disk drives, and set-top boxes.

 

Key electrical specifications include an input voltage range of 9V to 22V, a fixed 5V switching output, and a 3.3V LDO output with 700mA current capability. The operating temperature range is 0°C to 70°C.
