Integrated 12A and 20A DC-DC converters for point of load designs
Infineon Technologies has launched a family of four integrated DC-DC converters for point of load applications.
The TDA388xx family of synchronous buck regulator DC-DC converters from Infineon is aimed at server, AI, datacom, telecom, and storage applications with 12 A and 20 A currents.
The DC-DC converters use a fast constant on-time (COT) control scheme to optimize performance. This approach ensures rapid transient response, minimizes passive component count, and reduces board space, operating over a wide input voltage range from 4.0 V to 16 V.
An external bias supply and internal compensation further extends the application range in various DC-DC applications.
- POL DC-DC buck regulators address next-gen challenges
- AI power management DC-DC regulator adds fast PWM
The TDA388xx family of four buck regulators (TDA38812, TDA38813, TDA38825, and TDA38826) includes selectable switching frequencies and a soft-start functionality. The regulators also offer a programmable current limit for precise control. They support fixed frequency continuous conduction mode (FCCM) and discontinuous conduction mode (DCM). Additionally, voltage tracking is enabled through an external reference input. This flexibility is crucial for varying power system requirements. Together, these features contribute to the adaptability and efficiency of the regulator family.
The key to the TDA388xx series of DC-DC converters is its built-in protection features to ensure system safety during fault conditions. These include pre-bias startup and thermally compensated current limiting. Overvoltage protection (OVP) and undervoltage protection (UVP) are also built in as well as a thermal shutdown is included for added safety.
The TDA388xx family is housed in a ROHS-compliant QFN-21 package. It operates effectively over a temperature range of -40 to 125°C and is available now in a standard QFN-21 (3 mm x 4 mm) package.
