The Texas Instruments TPS51220RHBRG4 is a DC/DC switching controller designed for notebook computer systems and point-of-load applications in LCD TVs and MFPs. It operates with an input voltage range of 4.5 V to 28 V and provides an output voltage range of 1 V to 12 V.
This controller features D-CAP and current mode control, with a maximum output current of 20 A. It supports a fixed frequency PWM operation from 200 kHz to 1 MHz and offers a high duty cycle of up to 99%. Key features include selectable light load operation (Continuous / Auto Skip / Out-Of-Audio Skip), programmable droop compensation, adjustable soft start, and integrated bootstrap MOSFET.
The TPS51220RHBRG4 includes essential protections such as OCL/OVP/UVP/UVLO and non-latch thermal shutdown. It also provides a Powergood output for each channel. The device is available in a 32-pin VQFN package measuring 5 mm x 5 mm, suitable for surface mount applications.
Additional functionalities include frequency synchronization, phase interleaving with 180° phase shift between channels, and resistor or inductor DCR current sensing. The output discharge function is also available with a disable option.
