Description
The TPS1225C is a highly integrated power-management IC that combines two synchronous buck controllers along with dedicated 5 V and 3.3 V LDO outputs in a single package. It supports an input voltage range typically from about 5.5 V to 24 V and is purpose-built for modern computing and compact electronics that require multiple voltage rails with minimal external components.
Key features and benefits include:
-
Two independent synchronous buck channels capable of generating step-down voltages for major power rails (such as core logic, memory, etc).
-
Integrated 5 V and 3.3 V LDO regulators that provide always-on auxiliary rails for system standby, BIOS, or management subsystems.
-
Compact QFN or similar surface-mount package that helps reduce board space, component count and layout complexity.
-
Built-in protection features such as over-voltage protection (OVP), under-voltage lockout (UVLO), thermal shutdown, and sequencing control to ensure safe start-up and operation of the different rails.
-
Ideal for applications like notebook computers, ultrabooks, mini-PCs, embedded systems, and other high-density boards where multiple regulated voltages are needed from a single power source.
In practical use, the TPS1225C simplifies the power architecture by providing high-efficiency buck regulation for the main rails, while the integrated LDOs ensure the essential 5 V and 3.3 V rails are stable and always available (even in light-load or standby conditions). This makes it an excellent choice when designing boards with tight power budgets and limited layout area.
