Overview for Buck Controller (External Switch)

TI has a wide portfolio of DC/DC step-down buck controllers to help you meet your design targets. Choose between low to wide VIN, single to multiphase, and analog to PMBus/I2C depending on your design requirements.

3.3 V buck controller

Applications in this category typically feature power input from batteries, supercapacitors (2.7 V or higher), or PCI Express connectors (3.3 V).

12 V buck controller

Applications typically feature a nominal 12 V input rail as is commonly found in server/ communication systems, or a supercapacitor output found in storage and UPS applications.

19 V buck controller

Typical applications in this category are industrial systems with nominal 24 V input rails, or PC systems with a nominal 19 V input rail.

48 V buck controller

Applications in this category involve 48 V input buses found in Industrial and communication applications.

multiphase buck controller

Multiphase buck applications typically involve high output current, low output voltage, and tight voltage regulation required for ASIC/FPGA/DDR/DSP/CPU core rails.
