The Texas Instruments TPS51220RHBT is a 3-V to 28-V synchronous peak current mode buck controller suitable for notebook power systems and point-of-load applications in LCD TVs and MFPs. It features a wide input voltage range from 4.5V to 28V and an output voltage range from 1V to 12V.
This controller supports D-CAP and current mode operation, offering selectable light load operation (Continuous / Auto Skip / Out-Of-Audio Skip). Key electrical features include a maximum duty cycle of 99%, a typical quiescent current of 0.0013A, and a fixed frequency PWM operation from 200 kHz to 1 MHz. It also includes features like frequency synchronization, phase interleaving, power good output, and synchronous rectification.
The TPS51220RHBT is housed in a 32-VQFN (5x5 mm) package. It provides essential protections such as OCL/OVP/UVP/UVLO and thermal shutdown (non-latch). The device also offers programmable droop compensation and adjustable soft start.
Applications include notebook computer system and I/O bus power, as well as point-of-load in LCD TVs and MFPs.
