TPS51220 Description

Short technical summary and product information.

The Texas Instruments TPS51220 is an active DC/DC switching controller designed for notebook power applications. It operates with an input voltage range of 4.5 V to 28 V and can provide an output voltage from 1 V to 12 V, with a maximum output current of 20 A.

 

This controller features a fixed frequency PWM operation, selectable between 200 kHz and 1 MHz. It supports both D-CAP and current mode control, offering flexibility in design. Key features include light load efficiency, phase interleaving, power good output, and synchronous rectification. The device also includes comprehensive protection features such as OCL, OVP, UVP, and UVLO, along with non-latch thermal shutdown.

 

The TPS51220 is available in a 32-pin VQFN (RHB) package measuring 5 mm x 5 mm. Its selectable light load operation modes (Continuous, Auto Skip, Out-Of-Audio Skip) and programmable droop compensation enhance efficiency and performance in various operating conditions. Applications include notebook computer systems and point-of-load power for LCD TVs and MFPs.
