6A, Adjustable Frequency Synchronous Buck Regulator Evaluation Module



Texas Instruments  LM20146MHEVAL

The LM20146 is a full-featured synchronous buck switching regulator capable of driving up to 6A of load current. The ability to adjust the operating frequency from 250 kHz to 750 kHz gives the designer flexibility in component selection. The LM20146 is capable of converting an input voltage between 2.95V and 5.5V down to an output voltage as low as 0.8V. Fault protection features include cycle-by-cycle current limit, output power good, and output over-voltage protection. The dual function soft-start/tracking pin can be used to control the startup response of the LM20146, and the precision enable pin can be used to easily sequence the LM20146 in sequence-critical applications. The LM20146 is available in an eTSSOP-16 package with an exposed pad for enhanced thermal performance.
