By Texas Instruments 191
Texas Instruments's LM21305 is a full-featured 5 A synchronous buck regulator optimized for solution size, flexibility, and high conversion efficiency. High power density LM21305 designs are achieved via monolithic integration of the high-side and low-side power MOSFETs, high switching frequency, current-mode control, and optimized thermal design. The efficiency of the LM21305 is elevated at light loads with diode emulation mode operation and at heavy loads by optimal design of the MOSFET gate drivers to minimize switch dead-times and body-diode conduction losses.
