UCD7230PWP

DC DC Switching Controllers Overview

The UCD7230PWP is a digital control compatible synchronous buck gate driver manufactured by Texas Instruments. It integrates high-side and low-side drivers with a current sense conditioning amplifier for precise inductor current sensing. The device supports switching frequencies up to 2 MHz and operates within a supply voltage range of 4.5 V to 15.5 V. It features adjustable dead-time control, cycle-by-cycle current limiting, and thermal shutdown protection. The component is housed in a 20-PowerTSSOP package and is rated for an operating junction temperature from -40°C to 125°C.

DC DC Switching Controllers Feature Summary

• Integrates high-side and low-side gate drivers with a dedicated current sense conditioning amplifier for accurate inductor current monitoring.
• Supports digital control interfaces with programmable dead-time adjustment to optimize efficiency and prevent shoot-through.
• Includes comprehensive protection mechanisms such as cycle-by-cycle current limiting, under-voltage lockout, and thermal shutdown.

DC DC Switching Controllers Applications

• Digital power supplies utilizing DSP or FPGA controllers
• Server and workstation VRM designs
• Telecommunications point-of-load converters

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (PWP) confirms the 20-HTSSOP package and tube packaging variant. Confirm RoHS compliance status and check for obsolescence notices, as this part may be designated as not recommended for new designs. Ensure compatibility with existing PCB footprints and reflow profiles during sourcing.

DC DC Switching Controllers Selection Notes

Select this component when a synchronous buck topology requires integrated current sensing amplification alongside gate driving capabilities. It is suitable for applications demanding high switching frequencies and precise digital control loops. Consider alternative packages if board space constraints differ from the PowerTSSOP form factor.

DC DC Switching Controllers Part Context

The UCD7230 belongs to Texas Instruments' UCD723x family of synchronous buck gate drivers. This series is designed to simplify the design of digitally controlled power stages by combining driver functionality with signal conditioning. The PWP variant specifically denotes the through-hole compatible PowerTSSOP package option within this product line.

DC DC Switching Controllers Replacement Considerations

Check for UCD7230PWPR for reel packaging equivalents. Verify functional compatibility with UCD7230A variants regarding pinouts and electrical specifications before substitution.
