The TPS51220ARSNT from Texas Instruments is a dual synchronous buck regulator controller optimized for notebook computer system power supplies. It enables cost-effective solutions for 2-cell to 4-cell notebook power requirements.
This controller supports a wide input voltage range from 4.5 V to 32 V and provides adjustable output voltages from 1 V to 12 V. It features a high 99% duty cycle operation, contributing to high efficiency and fast transient response. The device operates with a fixed frequency that can be adjusted from 200 kHz to 1 MHz, with each channel running 180° out-of-phase for optimized performance.
The TPS51220ARSNT is available in a 32-pin QFN package (4x4mm) suitable for surface mounting. It operates within a temperature range of -40°C to 85°C. The controller includes various protection features such as OCL, OVP, UVP, UVLO, and thermal shutdown for reliable operation.
Applications include notebook computer system power and point-of-load in LCD TVs and MFPs. The controller offers selectable current or D-CAP mode architecture and supports resistor or inductor DCR current sensing.
