It operates from a 4.75 V to 15.5 V supply rail and switches between 200 kHz and 2 MHz, letting you balance inductor size against switching losses. The synchronous rectifier driver improves efficiency at higher output currents compared to a diode-rectified buck. Control features include current limiting and an enable pin for sequencing. ## Temperature range and environment Rated for a junction temperature range of -40°C to 125°C, this controller suits industrial motor drives, outdoor telecom power supplies, and under-hood automotive modules where ambient heat is a factor. The 20-VQFN package with exposed pad helps pull heat into the PCB ground plane — ensure your layout includes thermal vias under the pad to keep junction temperature within limits. ## Switching frequency — what it means for the BOM The 200 kHz to 2 MHz switching range gives you room to shrink magnetics at the high end or reduce switching losses at the low end. A 2 MHz design lets you use a smaller inductor and fewer output capacitors, saving board area in a compact power module. At 200 kHz you get better efficiency and lower EMI, at the cost of larger passives. The controller does not offer clock synchronization, so plan for beat-frequency management if multiple converters share a board. ## Lifecycle and sourcing The UCD7230ARGWT is listed as active with ROHS3 compliance.","metaTitle":"UCD7230ARGWT Buck Controller, 200kHz-2MHz, 20-VQFN","metaDescription":"TI UCD7230ARGWT step-down buck controller, 4.75V-15.5V supply, 200kHz-2MHz switching, -40°C to 125°C, 20-VQFN.
